General Description
"(2S)-1-[(4S)-4,5-dihydro-4-(phenylMethyl)-2-oxazolyl]-2-(diphenylphosphino)-Ferrocene" is a complex organic compound that involves several key chemical functional groups. It includes a ferrocene moiety, which is a sandwiched structure of an iron atom sandwiched between two cyclopentadienyl rings. In addition, this compound contains a 2-oxazolyl group, featuring a five-membered ring with one oxygen and one nitrogen atoms, and a phenylmethyl group, which consists of a benzene ring attached to a methyl group. Finally, it has a diphenylphosphino group, which includes a phosphorus atom bounded to two phenyl rings. The specific configuration of the stereochemistry is indicated by the (2S) and (4S) prefixes, denoting the specific spatial orientation of the different components.
Check Digit Verification of cas no
The CAS Registry Mumber 541540-58-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,1,5,4 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 541540-58:
(8*5)+(7*4)+(6*1)+(5*5)+(4*4)+(3*0)+(2*5)+(1*8)=133
133 % 10 = 3
So 541540-58-3 is a valid CAS Registry Number.

Kinetic resolution of racemic ferrocenylphosphine compounds by enantioselective oxidation using cyclic selenoxides having a chiral ligand
Miyake, Yoshihiro,Yamauchi, Akiyoshi,Nishibayashi, Yoshiaki,Uemura, Sakae
, p. 381 - 387 (2007/10/03)
Cyclic selenoxides having an optically active binaphthyl skeleton work as the reagents for enantioselective oxidation of phosphines to the corresponding phosphine oxides. Treatment of a racemic 2-oxazolin-2-ylferrocenylphosphine with one of the selenoxides in carbon tetrachloride in the presence of phenol affords the corresponding phosphine oxide together with the unreacted starting phosphine, both with moderate enantioselectivities (the phosphine oxide, up to 13% ee; the phosphine, up to 29% ee).
