Check Digit Verification of cas no

The CAS Registry Mumber 421-43-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 421-43:
(5*4)+(4*2)+(3*1)+(2*4)+(1*3)=42
42 % 10 = 2
So 421-43-2 is a valid CAS Registry Number.
