Check Digit Verification of cas no

The CAS Registry Mumber 1334682-44-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,6,8 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1334682-44:
(9*1)+(8*3)+(7*3)+(6*4)+(5*6)+(4*8)+(3*2)+(2*4)+(1*4)=158
158 % 10 = 8
So 1334682-44-8 is a valid CAS Registry Number.
