Check Digit Verification of cas no

The CAS Registry Mumber 4419-40-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,1 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4419-40:
(6*4)+(5*4)+(4*1)+(3*9)+(2*4)+(1*0)=83
83 % 10 = 3
So 4419-40-3 is a valid CAS Registry Number.
