Check Digit Verification of cas no

The CAS Registry Mumber 117286-14-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,2,8 and 6 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 117286-14:
(8*1)+(7*1)+(6*7)+(5*2)+(4*8)+(3*6)+(2*1)+(1*4)=123
123 % 10 = 3
So 117286-14-3 is a valid CAS Registry Number.
