Check Digit Verification of cas no

The CAS Registry Mumber 118617-31-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,6,1 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 118617-31:
(8*1)+(7*1)+(6*8)+(5*6)+(4*1)+(3*7)+(2*3)+(1*1)=125
125 % 10 = 5
So 118617-31-5 is a valid CAS Registry Number.
