Check Digit Verification of cas no

The CAS Registry Mumber 321-42-6 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 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 321-42:
(5*3)+(4*2)+(3*1)+(2*4)+(1*2)=36
36 % 10 = 6
So 321-42-6 is a valid CAS Registry Number.
