Check Digit Verification of cas no

The CAS Registry Mumber 81833-15-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,3 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81833-15:
(7*8)+(6*1)+(5*8)+(4*3)+(3*3)+(2*1)+(1*5)=130
130 % 10 = 0
So 81833-15-0 is a valid CAS Registry Number.
