Check Digit Verification of cas no

The CAS Registry Mumber 943149-81-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,3,1,4 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 943149-81:
(8*9)+(7*4)+(6*3)+(5*1)+(4*4)+(3*9)+(2*8)+(1*1)=183
183 % 10 = 3
So 943149-81-3 is a valid CAS Registry Number.
