Check Digit Verification of cas no

The CAS Registry Mumber 445-78-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,4 and 5 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 445-78:
(5*4)+(4*4)+(3*5)+(2*7)+(1*8)=73
73 % 10 = 3
So 445-78-3 is a valid CAS Registry Number.
