Check Digit Verification of cas no

The CAS Registry Mumber 33557-13-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,5,5 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 33557-13:
(7*3)+(6*3)+(5*5)+(4*5)+(3*7)+(2*1)+(1*3)=110
110 % 10 = 0
So 33557-13-0 is a valid CAS Registry Number.
