Check Digit Verification of cas no

The CAS Registry Mumber 18336-39-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,3,3 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 18336-39:
(7*1)+(6*8)+(5*3)+(4*3)+(3*6)+(2*3)+(1*9)=115
115 % 10 = 5
So 18336-39-5 is a valid CAS Registry Number.
