Check Digit Verification of cas no

The CAS Registry Mumber 143729-84-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,7,2 and 9 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 143729-84:
(8*1)+(7*4)+(6*3)+(5*7)+(4*2)+(3*9)+(2*8)+(1*4)=144
144 % 10 = 4
So 143729-84-4 is a valid CAS Registry Number.

New ampicillin derivatives with glyoxyloylbenzhydrazones as side chains

Heinisch,Hanschke,Willitzer,Mollmann,Tresselt,Stengel,Eckardt,Kleinwachter

, p. 412 - 415 (2007/10/02)

New ampicillin derivatives were synthesized from glyoxylic acid benzhydrazones by reaction with chloroformates via mixed anhydrides and ampicillin. These compounds were tested in an agar diffusion test against six different bacterial strains and also for their stability against β-lactamases. Studies about structure activity relationships have shown, that the activity against different bacterial strains is influenced in different manner by hydrophilic or hydrophobic and electronic properties of substituents.
