Check Digit Verification of cas no

The CAS Registry Mumber 79641-49-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,6,4 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 79641-49:
(7*7)+(6*9)+(5*6)+(4*4)+(3*1)+(2*4)+(1*9)=169
169 % 10 = 9
So 79641-49-9 is a valid CAS Registry Number.
