Check Digit Verification of cas no

The CAS Registry Mumber 22221-64-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,2,2 and 1 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 22221-64:
(7*2)+(6*2)+(5*2)+(4*2)+(3*1)+(2*6)+(1*4)=63
63 % 10 = 3
So 22221-64-3 is a valid CAS Registry Number.
