Check Digit Verification of cas no

The CAS Registry Mumber 1196913-32-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,6,9,1 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1196913-32:
(9*1)+(8*1)+(7*9)+(6*6)+(5*9)+(4*1)+(3*3)+(2*3)+(1*2)=182
182 % 10 = 2
So 1196913-32-2 is a valid CAS Registry Number.
