Check Digit Verification of cas no

The CAS Registry Mumber 29121-59-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,1,2 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 29121-59:
(7*2)+(6*9)+(5*1)+(4*2)+(3*1)+(2*5)+(1*9)=103
103 % 10 = 3
So 29121-59-3 is a valid CAS Registry Number.
