Check Digit Verification of cas no

The CAS Registry Mumber 718614-71-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,1,8,6,1 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 718614-71:
(8*7)+(7*1)+(6*8)+(5*6)+(4*1)+(3*4)+(2*7)+(1*1)=172
172 % 10 = 2
So 718614-71-2 is a valid CAS Registry Number.
