Check Digit Verification of cas no

The CAS Registry Mumber 81691-99-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,9 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81691-99:
(7*8)+(6*1)+(5*6)+(4*9)+(3*1)+(2*9)+(1*9)=158
158 % 10 = 8
So 81691-99-8 is a valid CAS Registry Number.
