Check Digit Verification of cas no

The CAS Registry Mumber 646-13-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 6 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 646-13:
(5*6)+(4*4)+(3*6)+(2*1)+(1*3)=69
69 % 10 = 9
So 646-13-9 is a valid CAS Registry Number.
