Check Digit Verification of cas no

The CAS Registry Mumber 121883-88-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,8,8 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 121883-88:
(8*1)+(7*2)+(6*1)+(5*8)+(4*8)+(3*3)+(2*8)+(1*8)=133
133 % 10 = 3
So 121883-88-3 is a valid CAS Registry Number.
