41855-95-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 41855-95-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,8,5 and 5 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 41855-95:
(7*4)+(6*1)+(5*8)+(4*5)+(3*5)+(2*9)+(1*5)=132
132 % 10 = 2
So 41855-95-2 is a valid CAS Registry Number.

NHC-Catalyzed Aza-Benzoin Condensation of N, N′-Dipyridin-2-yl Aminals with Aldehydes

Lamb, Justin S.,Takashima, Ryo,Suzuki, Yumiko

, p. 10224 - 10234 (2021/08/16)

α-Amino ketones are useful compounds because of their synthetic utility and bioactivities. After observing the ability of N,N′-dipyridin-2-yl aminals to form imines in situ, the synthesis of α-amino ketones using N,N′-dipyridin-2-yl aminals was proposed.

CONDENSATION REACTIONS BETWEEN AROMATIC ALDEHYDES AND SOME HETEROCYCLIC AROMATIC AMINES

Forlani, Luciano,Sintoni, Marina,Todesco, Paolo E.

, p. 229 - 232 (2007/10/02)

1,1-Diamino derivatives are obtained by means of reactions between 2-aminothiazole and aromatic aldehydes carried out in methanol (and in dimethyl sulphoxide).The reaction of amine with the C=N of imine occurs without catalyst and is an easier process than its addition to C=O.This behaviour is also displayed by a number of aromatic heterocycles and homocyclic amines and may be explained by considering the activating effect of the electron-withdrawing group present in the imine moiety.
