Check Digit Verification of cas no

The CAS Registry Mumber 1339943-12-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,9,9,4 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1339943-12:
(9*1)+(8*3)+(7*3)+(6*9)+(5*9)+(4*4)+(3*3)+(2*1)+(1*2)=182
182 % 10 = 2
So 1339943-12-2 is a valid CAS Registry Number.
