Check Digit Verification of cas no

The CAS Registry Mumber 135644-36-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,6,4 and 4 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 135644-36:
(8*1)+(7*3)+(6*5)+(5*6)+(4*4)+(3*4)+(2*3)+(1*6)=129
129 % 10 = 9
So 135644-36-9 is a valid CAS Registry Number.
