116400-74-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 116400-74-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,4,0 and 0 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 116400-74:
(8*1)+(7*1)+(6*6)+(5*4)+(4*0)+(3*0)+(2*7)+(1*4)=89
89 % 10 = 9
So 116400-74-9 is a valid CAS Registry Number.

A mild dihydrobenzooxaphosphole oxazoline/iridium catalytic system for asymmetric hydrogenation of unfunctionalized dialins

Qu, Bo,Samankumara, Lalith P.,Ma, Shengli,Frick, Keith R.,Desrosiers, Jean-Nicolas,Rodriguez, Sonia,Li, Zhibin,Haddad, Nizar,Han, Zhengxu S.,McKellop, Keith,Pennino, Scott,Grinberg, Nelu,Gonnella, Nina C.,Song, Jinhua J.,Senanayake, Chris H.

, p. 14428 - 14432 (2015/02/19)

Air-stable P-chiral dihydrobenzooxaphosphole oxazoline ligands were designed and synthesized. When they were used in the iridium-catalyzed asymmetric hydrogenation of unfunctionalized 1-aryl-3,4-dihydronaphthalenes under one atmosphere pressure of H2, up to 99:1 e.r. was obtained. High enantioselectivities were also observed in the reduction of the exocyclic imine derivatives of 1-tetralones.
