Check Digit Verification of cas no

The CAS Registry Mumber 13664-91-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,6 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 13664-91:
(7*1)+(6*3)+(5*6)+(4*6)+(3*4)+(2*9)+(1*1)=110
110 % 10 = 0
So 13664-91-0 is a valid CAS Registry Number.
