Check Digit Verification of cas no

The CAS Registry Mumber 129831-74-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,8,3 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 129831-74:
(8*1)+(7*2)+(6*9)+(5*8)+(4*3)+(3*1)+(2*7)+(1*4)=149
149 % 10 = 9
So 129831-74-9 is a valid CAS Registry Number.
