Check Digit Verification of cas no

The CAS Registry Mumber 56663-76-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,6,6 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 56663-76:
(7*5)+(6*6)+(5*6)+(4*6)+(3*3)+(2*7)+(1*6)=154
154 % 10 = 4
So 56663-76-4 is a valid CAS Registry Number.
