Check Digit Verification of cas no

The CAS Registry Mumber 1159692-05-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,9,6,9 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1159692-05:
(9*1)+(8*1)+(7*5)+(6*9)+(5*6)+(4*9)+(3*2)+(2*0)+(1*5)=183
183 % 10 = 3
So 1159692-05-3 is a valid CAS Registry Number.
