Check Digit Verification of cas no

The CAS Registry Mumber 156126-13-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,1,2 and 6 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 156126-13:
(8*1)+(7*5)+(6*6)+(5*1)+(4*2)+(3*6)+(2*1)+(1*3)=115
115 % 10 = 5
So 156126-13-5 is a valid CAS Registry Number.
