849589-04-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 849589-04-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,9,5,8 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 849589-04:
(8*8)+(7*4)+(6*9)+(5*5)+(4*8)+(3*9)+(2*0)+(1*4)=234
234 % 10 = 4
So 849589-04-4 is a valid CAS Registry Number.

Construction of quaternary carbon stereocentres: Catalytic enantioselective allylation assisted by a bimetallic catalytic system

Nowicki, Audrey,Mortreux, Andre,Agbossou-Niedercorn, Francine

, p. 1295 - 1298 (2005)

The asymmetric allylic alkylation of prochiral aryl cyano esters has been carried out in the presence of a bi-component catalytic system containing a palladium and a rhodium complex modified by phosphorus containing chiral auxiliaries. The allyl derivativ

Highly selective preparation of a chiral quaternary allyl aryl piperidinedione by palladium-catalyzed asymmetric allylation under solid-liquid phase-transfer catalysis

Nowicki, Audrey,Keldenich, Jerome,Agbossou-Niedercorn, Francine

, p. 6124 - 6127 (2008/09/17)

The combination of a chiral palladium catalyst and a solid-liquid phase-transfer catalyst provides an effective method for the chemo- and enantioselective preparation of the chiral quaternary center of an allyl aryl piperidinedione. Wiley-VCH Verlag GmbH
