Check Digit Verification of cas no

The CAS Registry Mumber 912291-94-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,2,2,9 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 912291-94:
(8*9)+(7*1)+(6*2)+(5*2)+(4*9)+(3*1)+(2*9)+(1*4)=162
162 % 10 = 2
So 912291-94-2 is a valid CAS Registry Number.
