Check Digit Verification of cas no

The CAS Registry Mumber 40331-80-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,3,3 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 40331-80:
(7*4)+(6*0)+(5*3)+(4*3)+(3*1)+(2*8)+(1*0)=74
74 % 10 = 4
So 40331-80-4 is a valid CAS Registry Number.
