Check Digit Verification of cas no

The CAS Registry Mumber 1269217-99-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,9,2,1 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1269217-99:
(9*1)+(8*2)+(7*6)+(6*9)+(5*2)+(4*1)+(3*7)+(2*9)+(1*9)=183
183 % 10 = 3
So 1269217-99-3 is a valid CAS Registry Number.
