Check Digit Verification of cas no

The CAS Registry Mumber 133157-91-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,1,5 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 133157-91:
(8*1)+(7*3)+(6*3)+(5*1)+(4*5)+(3*7)+(2*9)+(1*1)=112
112 % 10 = 2
So 133157-91-2 is a valid CAS Registry Number.
