Check Digit Verification of cas no

The CAS Registry Mumber 80447-43-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,4,4 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 80447-43:
(7*8)+(6*0)+(5*4)+(4*4)+(3*7)+(2*4)+(1*3)=124
124 % 10 = 4
So 80447-43-4 is a valid CAS Registry Number.
