Check Digit Verification of cas no

The CAS Registry Mumber 333421-13-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,3,4,2 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 333421-13:
(8*3)+(7*3)+(6*3)+(5*4)+(4*2)+(3*1)+(2*1)+(1*3)=99
99 % 10 = 9
So 333421-13-9 is a valid CAS Registry Number.
