Check Digit Verification of cas no

The CAS Registry Mumber 712-24-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,1 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 712-24:
(5*7)+(4*1)+(3*2)+(2*2)+(1*4)=53
53 % 10 = 3
So 712-24-3 is a valid CAS Registry Number.
