Check Digit Verification of cas no

The CAS Registry Mumber 133617-15-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,6,1 and 7 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 133617-15:
(8*1)+(7*3)+(6*3)+(5*6)+(4*1)+(3*7)+(2*1)+(1*5)=109
109 % 10 = 9
So 133617-15-9 is a valid CAS Registry Number.
