Check Digit Verification of cas no

The CAS Registry Mumber 173345-36-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,3,4 and 5 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 173345-36:
(8*1)+(7*7)+(6*3)+(5*3)+(4*4)+(3*5)+(2*3)+(1*6)=133
133 % 10 = 3
So 173345-36-3 is a valid CAS Registry Number.
