Check Digit Verification of cas no

The CAS Registry Mumber 331663-55-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,6,6 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 331663-55:
(8*3)+(7*3)+(6*1)+(5*6)+(4*6)+(3*3)+(2*5)+(1*5)=129
129 % 10 = 9
So 331663-55-9 is a valid CAS Registry Number.
