Check Digit Verification of cas no

The CAS Registry Mumber 921-22-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,2 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 921-22:
(5*9)+(4*2)+(3*1)+(2*2)+(1*2)=62
62 % 10 = 2
So 921-22-2 is a valid CAS Registry Number.
