404-19-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 404-19-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,0 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 404-19:
(5*4)+(4*0)+(3*4)+(2*1)+(1*9)=43
43 % 10 = 3
So 404-19-3 is a valid CAS Registry Number.
