4357-28-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4357-28-2 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, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4357-28:
(6*4)+(5*3)+(4*5)+(3*7)+(2*2)+(1*8)=92
92 % 10 = 2
So 4357-28-2 is a valid CAS Registry Number.

Directed: Ortho C-H borylation catalyzed using Cp?Rh(iii)-NHC complexes

Thongpaen, Jompol,Schmid, Thibault E.,Toupet, Loic,Dorcet, Vincent,Mauduit, Marc,Baslé, Olivier

supporting information, p. 8202 - 8205 (2018/07/29)

Cp?Rh(NHC) complexes with bulky chiral bidentate NHC-carboxylate ligands were efficiently synthesized and fully characterized including solid-state structures. These unprecedented rhodium(iii) complexes demonstrated high selectivity in pyridine-directed ortho-C-H borylation of arenes under mild conditions.

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
