Check Digit Verification of cas no

The CAS Registry Mumber 119879-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,8,7 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 119879-91:
(8*1)+(7*1)+(6*9)+(5*8)+(4*7)+(3*9)+(2*9)+(1*1)=183
183 % 10 = 3
So 119879-91-3 is a valid CAS Registry Number.
