73728-29-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 73728-29-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,7,2 and 8 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 73728-29:
(7*7)+(6*3)+(5*7)+(4*2)+(3*8)+(2*2)+(1*9)=147
147 % 10 = 7
So 73728-29-7 is a valid CAS Registry Number.

Investigation of Ion-Molecular Reactions of Nucleogenic Phenyl Cations with 1,4-Diazine Derivatives

Shchepina,Avrorin,Badun,Vasyanin,Shurov,Agafonova

, p. 1595 - 1601 (2015)

The use of nuclear-chemical synthesis, based on the generation of free nucleogenic phenyl cations, allowed for the direct phenylation of the nitrogen atom in 1,4-diazines. The presence of two methyl substituents in the quinoxaline substrate leads to a mar

Preparation of n-phenylbenzo[h]quinolinium derivatives labeled with tritium

Shchepina,Avrorin,Badun,Boiko

, p. 1196 - 1199 (2012)

The possibility of a direct phenylation of benzoquinoline nitrogen atom with nucleogenic phenyl cations has been demonstrated. A simple method has been developed for obtaining previously unknown tritium labeled N-phenyl derivatives of benzo[h]quinolinium, which are promising radioactive markers for studying the biological action mechanisms of medicinal substances containing the benzoquinolinium structure.
