Check Digit Verification of cas no

The CAS Registry Mumber 32431-84-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,4,3 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 32431-84:
(7*3)+(6*2)+(5*4)+(4*3)+(3*1)+(2*8)+(1*4)=88
88 % 10 = 8
So 32431-84-8 is a valid CAS Registry Number.

Fluorinated Dithienylethene-Naphthalenediimide Copolymers for High-Mobility n-Channel Field-Effect Transistors

Chen, Zhihui,Zhang, Weifeng,Huang, Jianyao,Gao, Dong,Wei, Congyuan,Lin, Zuzhang,Wang, Liping,Yu, Gui

, p. 6098 - 6107 (2017/08/29)

We develop two donor-acceptor copolymers based on a fluorinated dithienylethene building block, namely PNFDTE1 and PNFDTE2, in which naphthalenediimide (NDI) acts as an acceptor unit. Thermogravimetric analysis displayed both copolymers having good thermal stability with high decomposition temperatures over 400 °C. Broad absorption spectra were observed in the UV-vis-NIR region, with the absorption maxima being 720 and 724 nm for PNFDTE1 and PNFDTE2, respectively. Cyclic voltammetry tests exhibited deep-lying lowest unoccupied molecular orbital energy levels of ca. -4.0 eV. Two-dimensional grazing incidence X-ray diffraction patterns showed that different packing modes for two polymers result in the variation in charge transport properties. Backbone fluorination effectively decreases electron injection barrier, thereby facilitating electron mobility. An impressive electron mobility of 3.20 cm2 V-1 s-1 was achieved in air for PNFDTE1-based polymer field-effect transistors fabricated on the poly(ethylene terephthalate) substrate. The mobility value is almost the highest for NDI-containing polymers on the flexible substrate. This work provides a guideline for design and synthesis of fluorinated semiconductors that enables control of charge-transport polarity.

Methods and compositions are provided for forming complexes between dsDNA and novel DNA-binding polymers comprising N-terminal thiophene-containing moieties which exhibit selectivity for T-A base pairs. By appropriate choice of target sequences and DNA-binding polymers, complexes comprising polymer-DNA are obtained with high association constants. The formation of complexes can be used for identification of specific dsDNA sequences, for inhibiting gene transcription, and as a therapeutic for inhibiting proliferation of undesired cells or modulation of expression of specific genes.

A facile and improved synthesis of 3-fluorothiophene

Pomerantz, Martin,Turkman, Nashaat

experimental part, p. 2333 - 2336 (2009/04/05)

A new efficient and convenient route to 3-fluorothiophene in four steps and 49% overall yield is reported. The fluorine atom was successfully introduced into the thiophene ring in 67% yield using the Schiemann reaction on 2-methoxycarbonylthiophene-3-diazonium tetrafluoroborate. The product, methyl 3-fluorothiophene-2-carboxylate was saponified and the 3-fluorothiophene-2- carboxylic acid was decarboxylated to afford 3-fluorothiophene in 93% yield.

Shape selective recognition of T·A base pairs by hairpin polyamides containing N-terminal 3-methoxy (and 3-Chloro) thiophene residues

Foister, Shane,Marques, Michael A.,Doss, Raymond M.,Dervan, Peter B.

, p. 4333 - 4340 (2007/10/03)

Hairpin polyamides selectively recognize predetermined DNA sequences with affinities comparable to naturally occurring proteins. Internal side-by-side pairs of unsymmetrical aromatic rings within the minor groove of DNA distinguish each of the four Watson-Crick base pairs. In contrast, N-terminal ring pairs exhibit less specificity, with the exception of Im/Py targeting G·C base pairs. In an effort to explore the sequence specificity of new ring pairs, a series of hairpin polyamides containing 3-substituted-thiophene-2-carboxamide residues at the N-terminus was synthesized. An N-terminal 3-methoxy (or 3-chloro) thiophene residue paired opposite Py displayed 6- (and 3-) fold selectivity for T·A relative to A·T base pair, while disfavoring G,C base pairs by >200-fold. Our data suggests shape selective recognition with projection of the 3-thiophene substituent (methoxy or chloro) to the floor of the minor groove.
