Check Digit Verification of cas no

The CAS Registry Mumber 1334782-08-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,7,8 and 2 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1334782-08:
(9*1)+(8*3)+(7*3)+(6*4)+(5*7)+(4*8)+(3*2)+(2*0)+(1*8)=159
159 % 10 = 9
So 1334782-08-9 is a valid CAS Registry Number.
