Check Digit Verification of cas no

The CAS Registry Mumber 1239338-74-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,3,3 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1239338-74:
(9*1)+(8*2)+(7*3)+(6*9)+(5*3)+(4*3)+(3*8)+(2*7)+(1*4)=169
169 % 10 = 9
So 1239338-74-9 is a valid CAS Registry Number.
