Check Digit Verification of cas no

The CAS Registry Mumber 80-23-9 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 80-23:
(4*8)+(3*0)+(2*2)+(1*3)=39
39 % 10 = 9
So 80-23-9 is a valid CAS Registry Number.
