Check Digit Verification of cas no

The CAS Registry Mumber 3330-24-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,3 and 0 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3330-24:
(6*3)+(5*3)+(4*3)+(3*0)+(2*2)+(1*4)=53
53 % 10 = 3
So 3330-24-3 is a valid CAS Registry Number.
