69657-27-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 69657-27-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,6,5 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 69657-27:
(7*6)+(6*9)+(5*6)+(4*5)+(3*7)+(2*2)+(1*7)=178
178 % 10 = 8
So 69657-27-8 is a valid CAS Registry Number.

Pseudo enantiomeric mixed S/P ligands derived from carbohydrates for the 1,4-addition of phenyl boronic acid to cyclohexenone

Valdivia,Bilbao,Moya,Rosales-Barrios,Salvador,Recio,Fernández,Khiar

, p. 3041 - 3047 (2016)

The application of phosphinite-thioglycosides and phosphine-thioglycosides ligands in Rh(i)-catalyzed 1,4-addition of phenylboronic acid to cyclohexenone is reported. Among the ligands tested, phosphinite-thioglycoside 3 and phosphine-thioglycoside 10, be

Cobalt-Catalyzed Asymmetric 1,4-Hydroboration of Enones with HBpin

Ren, Xiang,Lu, Zhan

, p. 8370 - 8374 (2021/11/01)

Herein, a series of new 8-OIQ cobalt complexes were synthesized and used for cobalt-catalyzed chemo- and enantioselective 1,4-hydroboration of enones with HBpin to access chiral β,β-disubstituted ketones with good to excellent chemo- and enantioselectivties. This protocol is operationally simple and shows a broad substrate scope.

Electronically deficient (Rax,S,S)-F12-C3-TunePhos and its applications in asymmetric 1,4-addition reactions

Hu, Shu-Bo,Chen, Zhang-Pei,Zhou, Ji,Zhou, Yong-Gui

supporting information, p. 1925 - 1929 (2016/04/19)

A novel electronically deficient chiral diphosphine ligand (Rax,S,S)-F12-C3-TunePhos has been concisely synthesized. The electron-poor ligand features both chiral centers and chiral axis bearing fluoro-functional groups on
