Check Digit Verification of cas no

The CAS Registry Mumber 81932-08-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,3 and 2 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 81932-08:
(7*8)+(6*1)+(5*9)+(4*3)+(3*2)+(2*0)+(1*8)=133
133 % 10 = 3
So 81932-08-3 is a valid CAS Registry Number.
