Check Digit Verification of cas no

The CAS Registry Mumber 4505-09-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,0 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4505-09:
(6*4)+(5*5)+(4*0)+(3*5)+(2*0)+(1*9)=73
73 % 10 = 3
So 4505-09-3 is a valid CAS Registry Number.
