4357-32-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4357-32-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,5 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4357-32:
(6*4)+(5*3)+(4*5)+(3*7)+(2*3)+(1*2)=88
88 % 10 = 8
So 4357-32-8 is a valid CAS Registry Number.

Cross-coupling study of iodo/chloropyridines and 2-chloroquinoline with atom-economic triarylbismuth reagents under Pd-catalysis

Rao, Maddali L.N.,Dhanorkar, Ritesh J.

, p. 338 - 349 (2015/03/04)

This study describes the palladium-catalyzed couplings of iodopyridines, chloropyridines, and chloroquinoline with atom-economic BiAr3 reagents in sub-stoichiometric loadings. Mono-arylations of iodo and chloropyridines produced arylpyridines i

A FACILE SYNTHESIS OF 3-(2-AMINO-4-ETHOXYPHENYL)PYRIDINE

Shibuya, Kimiyuki,Shigyo, Hiromichi,Ohta, Tomio

, p. 427 - 433 (2007/10/02)

A facile and efficient synthesis of 3-(2-amino-4-ethoxyphenyl)pyridine (6), a key intermediate of the antiarrhythmic agents, has been developed starting from 3-bromopyridine (2) by the benzyne reaction using sodium benzylamide as the key step.
