Check Digit Verification of cas no

The CAS Registry Mumber 118494-29-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,4,9 and 4 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 118494-29:
(8*1)+(7*1)+(6*8)+(5*4)+(4*9)+(3*4)+(2*2)+(1*9)=144
144 % 10 = 4
So 118494-29-4 is a valid CAS Registry Number.
