Check Digit Verification of cas no

The CAS Registry Mumber 332149-55-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,2,1,4 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 332149-55:
(8*3)+(7*3)+(6*2)+(5*1)+(4*4)+(3*9)+(2*5)+(1*5)=120
120 % 10 = 0
So 332149-55-0 is a valid CAS Registry Number.
