Check Digit Verification of cas no

The CAS Registry Mumber 17516-81-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,5,1 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 17516-81:
(7*1)+(6*7)+(5*5)+(4*1)+(3*6)+(2*8)+(1*1)=113
113 % 10 = 3
So 17516-81-3 is a valid CAS Registry Number.
