157246-90-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 157246-90-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,2,4 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 157246-90:
(8*1)+(7*5)+(6*7)+(5*2)+(4*4)+(3*6)+(2*9)+(1*0)=147
147 % 10 = 7
So 157246-90-7 is a valid CAS Registry Number.

Screening of a modular sugar-based phosphite-oxazoline ligand library in asymmetric Pd-catalyzed Heck reactions

Mata, Yvette,Pàmies, Oscar,Diéguez, Montserrat

, p. 3296 - 3304 (2007)

We have synthesised a library of phosphite-oxazoline ligands derived from readily available D-glucosamine. These ligands have been successfully screened in the palladium-catalysed Heck reaction of several substrates with high regio- (up to 99%) and enanti

An efficient phosphorus-containing oxazoline ligand derived from cis-2-amino-3,3-dimethyl-1-indanol: Application to the palladium-catalyzed asymmetric Heck reaction

Hashimoto, Yukihiko,Horie, Yumi,Hayashi, Minoru,Saigo, Kazuhiko

, p. 2205 - 2210 (2000)

Enantiopure 2-[2-(diphenylphosphino)phenyl]oxazoline, derived from a non-natural chiral aminoalcohol, cis-2-amino-3,3-dimethyl-1-indanol, was found to be an efficient ligand for the palladium-catalyzed asymmetric Heck reaction. Copyright (C) 2000 Elsevier
