Check Digit Verification of cas no

The CAS Registry Mumber 328-64-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,2 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 328-64:
(5*3)+(4*2)+(3*8)+(2*6)+(1*4)=63
63 % 10 = 3
So 328-64-3 is a valid CAS Registry Number.
