Check Digit Verification of cas no

The CAS Registry Mumber 117182-71-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,1,8 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 117182-71:
(8*1)+(7*1)+(6*7)+(5*1)+(4*8)+(3*2)+(2*7)+(1*1)=115
115 % 10 = 5
So 117182-71-5 is a valid CAS Registry Number.
