Check Digit Verification of cas no

The CAS Registry Mumber 115979-13-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,9,7 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 115979-13:
(8*1)+(7*1)+(6*5)+(5*9)+(4*7)+(3*9)+(2*1)+(1*3)=150
150 % 10 = 0
So 115979-13-0 is a valid CAS Registry Number.
