Check Digit Verification of cas no

The CAS Registry Mumber 138258-77-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,2,5 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138258-77:
(8*1)+(7*3)+(6*8)+(5*2)+(4*5)+(3*8)+(2*7)+(1*7)=152
152 % 10 = 2
So 138258-77-2 is a valid CAS Registry Number.

P-aryl-diphenylphospholanes and their phospholanium salts as efficient monodentate ligands for asymmetric rhodium-catalyzed hydrogenation

Dobrota, Cristian,Fiaud, Jean-Claud,Toffano, Martial

, p. 144 - 148 (2015/03/04)

Enantiopure P-aryl-2,5-diphenylphospholanes and its corresponding P-aryl-phospholanium salt appear as very efficient ligands for rhodium-catalyzed asymmetric hydrogenation reaction with similar activities and enantioselectivities. The hydrogenation product was obtained in good enantiomeric excesses (up to 93% ee ) in only few minutes under an atmospheric pressure of dihydrogen. The excellent activity of the catalyst can be explained by a constant and high TOF value during the reaction.

Olefination of ketenes for the enantioselective synthesis of allenes via an ylide route

Pseudo-C2-symmetric chiral phosphorus ylides have been designed and synthesized for the enantioselective preparation of allenic esters, and up to 92% ee has been achieved. The Royal Society of Chemistry 2006.

Synthesis and first applications of a new family of chiral monophosphine ligand: 2,5-diphenylphosphospholanes

Guillen, Frédéric,Rivard, Michael,Toffano, Martial,Legros, Jean-Yves,Daran, Jean-Claude,Fiaud, Jean-Claude

, p. 5895 - 5904 (2007/10/03)

The cyclic phosphinic acid 1-hydroxy-1-r-oxo-2c,5-t-diphenylphospholane was synthesized and resolved into enantiomers through fractional crystallization of the quinine salts. The P-phenyl, P-methyl and P-benzyl tertiary phosphine oxides were obtained from
