Check Digit Verification of cas no

The CAS Registry Mumber 64285-36-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,2,8 and 5 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 64285-36:
(7*6)+(6*4)+(5*2)+(4*8)+(3*5)+(2*3)+(1*6)=135
135 % 10 = 5
So 64285-36-5 is a valid CAS Registry Number.
