Check Digit Verification of cas no

The CAS Registry Mumber 66221-12-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,2,2 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 66221-12:
(7*6)+(6*6)+(5*2)+(4*2)+(3*1)+(2*1)+(1*2)=103
103 % 10 = 3
So 66221-12-3 is a valid CAS Registry Number.
