Check Digit Verification of cas no

The CAS Registry Mumber 221528-18-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,5,2 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 221528-18:
(8*2)+(7*2)+(6*1)+(5*5)+(4*2)+(3*8)+(2*1)+(1*8)=103
103 % 10 = 3
So 221528-18-3 is a valid CAS Registry Number.
