Check Digit Verification of cas no

The CAS Registry Mumber 23330-03-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,3,3 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 23330-03:
(7*2)+(6*3)+(5*3)+(4*3)+(3*0)+(2*0)+(1*3)=62
62 % 10 = 2
So 23330-03-2 is a valid CAS Registry Number.
