92419-65-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 92419-65-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,4,1 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 92419-65:
(7*9)+(6*2)+(5*4)+(4*1)+(3*9)+(2*6)+(1*5)=143
143 % 10 = 3
So 92419-65-3 is a valid CAS Registry Number.

Diastereoselectivities in the Diels-Alder reactions of cyclopentadiene with optically active dimenthyl fumarate and menthyl methyl fumarate in LiClO4/ether and on Al2O3

Bains,Pagni,Kabalka,Pala

, p. 821 - 834 (1994)

Reactions of cyclopentadiene with (-)-dimenthyl fumarate, which yield adducts 1 and 2, and with (-)-menthyl methyl fumarate, which yield adducts 3 through 6, were carried out on alumina activated at different temperatures, in LiClO4/ether solut

Asymmetric Diels-Alder reaction of unsymmetrical maleates. A chemical access to chiral, unsymmetrical cis-cyclohexene-1,2-dicarboxylates

Maruoka, Keiji,Akakura, Matsujiro,Saito, Susumu,Ooi, Takashi,Yamamoto, Hisashi

, p. 6153 - 6158 (2007/10/02)

A new route to optically active, unsymmetrical cis-cyclohexene-1,2-dicarboxylate derivatives has been developed on the basis of the asymmetric Diels-Alder reaction of chiral, unsymmetrical maleates catalyzed by certain Lewis acids. A notably high level of asymmetric induction has been observed in the asymmetric Diels-Alder reaction of unsymmetrical maleates possessing chiral auxiliaries such as α-phenethyl and trans-2-phenylcyclohexyl groups. The origin of the chiral outcome using these dienophiles has been elucidated.

Chiral Induction in Photochemical Reactions, VI. - Asymmetric Control of the Addition of Hemipinacol Radicals to Chiral Maleates and Fumarates

Vassen, Reiner,Runsink, Jan,Scharf, Hans-Dieter

, p. 3492 - 3497 (2007/10/02)

The photocatalysed addition of 2-propanol (2) to the monoesters of maleic acid 1b and 1d yields the esters of terebic acid 5b and 5d with a diastereoselectivity up to 62percent de.The major diastereomer 5d has (2S)-configuration.Diastereoselectivity of 23
