Check Digit Verification of cas no

The CAS Registry Mumber 4550-43-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,5 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4550-43:
(6*4)+(5*5)+(4*5)+(3*0)+(2*4)+(1*3)=80
80 % 10 = 0
So 4550-43-0 is a valid CAS Registry Number.
