Check Digit Verification of cas no

The CAS Registry Mumber 118665-95-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,6,6 and 5 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 118665-95:
(8*1)+(7*1)+(6*8)+(5*6)+(4*6)+(3*5)+(2*9)+(1*5)=155
155 % 10 = 5
So 118665-95-5 is a valid CAS Registry Number.
