Check Digit Verification of cas no

The CAS Registry Mumber 236117-68-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,6,1,1 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 236117-68:
(8*2)+(7*3)+(6*6)+(5*1)+(4*1)+(3*7)+(2*6)+(1*8)=123
123 % 10 = 3
So 236117-68-3 is a valid CAS Registry Number.
