Check Digit Verification of cas no

The CAS Registry Mumber 91156-81-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,1,5 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 91156-81:
(7*9)+(6*1)+(5*1)+(4*5)+(3*6)+(2*8)+(1*1)=129
129 % 10 = 9
So 91156-81-9 is a valid CAS Registry Number.
