Check Digit Verification of cas no

The CAS Registry Mumber 139698-81-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,9 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139698-81:
(8*1)+(7*3)+(6*9)+(5*6)+(4*9)+(3*8)+(2*8)+(1*1)=190
190 % 10 = 0
So 139698-81-0 is a valid CAS Registry Number.
