745813-62-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 745813-62-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,5,8,1 and 3 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 745813-62:
(8*7)+(7*4)+(6*5)+(5*8)+(4*1)+(3*3)+(2*6)+(1*2)=181
181 % 10 = 1
So 745813-62-1 is a valid CAS Registry Number.

Dramatic ligand effect in catalytic asymmetric reductive aldol reaction of allenic esters to ketones

Zhao, Dongbo,Oisaki, Kounosuke,Kanai, Motomu,Shibasaki, Masakatsu

, p. 14440 - 14441 (2006)

A general catalytic asymmetric reductive aldol reaction of allenic esters to ketones is described. Two distinct constitutional isomers were selectively produced depending on the reaction conditions. A combination of CuOAc/(R)-DTBM-SEGPHOS/PCy3

The mechanism and an improved asymmetric allylboration of ketones catalyzed by chiral biphenols

Barnett, David S.,Moquist, Philip N.,Schaus, Scott E.

supporting information; experimental part, p. 8679 - 8682 (2010/02/28)

Giving it a boost: A mechanistic study of the enantioselective asymmetric titled reaction with allyldiisopropoxyborane catalyzed by chiral biphenols revealed a key ligand exchange process which liberates isopropyl alcohol. The addition of iPrOH to the rea

Catalytic enantioselective allylboration of ketones

Wada, Reiko,Oisaki, Kounosuke,Kanai, Motomu,Shibasaki, Masakatsu

, p. 8910 - 8911 (2007/10/03)

The first example of catalytic enantioselective allylboration and crotylboration of simple ketones is described. High enantioselectivity (up to 93% ee) was obtained using 3 mol % CuF-iPr-DuPHOS as a chiral catalyst and 4.5 mol % La(Oi/sup
