Check Digit Verification of cas no

The CAS Registry Mumber 840-49-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,4 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 840-49:
(5*8)+(4*4)+(3*0)+(2*4)+(1*9)=73
73 % 10 = 3
So 840-49-3 is a valid CAS Registry Number.
