Check Digit Verification of cas no

The CAS Registry Mumber 1424-81-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,2 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1424-81:
(6*1)+(5*4)+(4*2)+(3*4)+(2*8)+(1*1)=63
63 % 10 = 3
So 1424-81-3 is a valid CAS Registry Number.
