Check Digit Verification of cas no

The CAS Registry Mumber 80-76-2 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, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 80-76:
(4*8)+(3*0)+(2*7)+(1*6)=52
52 % 10 = 2
So 80-76-2 is a valid CAS Registry Number.
