Check Digit Verification of cas no

The CAS Registry Mumber 1174147-49-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,4,1,4 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1174147-49:
(9*1)+(8*1)+(7*7)+(6*4)+(5*1)+(4*4)+(3*7)+(2*4)+(1*9)=149
149 % 10 = 9
So 1174147-49-9 is a valid CAS Registry Number.
