Check Digit Verification of cas no

The CAS Registry Mumber 173221-15-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,2,2 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 173221-15:
(8*1)+(7*7)+(6*3)+(5*2)+(4*2)+(3*1)+(2*1)+(1*5)=103
103 % 10 = 3
So 173221-15-3 is a valid CAS Registry Number.
