212626-89-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 212626-89-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,6,2 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 212626-89:
(8*2)+(7*1)+(6*2)+(5*6)+(4*2)+(3*6)+(2*8)+(1*9)=116
116 % 10 = 6
So 212626-89-6 is a valid CAS Registry Number.

Intramolecular Anti-Carbolithiation of Alkynes: Stereo-Directing Effect of Lithium-Coordinating Substituents

Ly, Kim Uyen,Boussonnière, Anne,Castanet, Anne-Sophie

supporting information, (2022/01/19)

This paper presents the results of our investigations on the stereochemical course of intramolecular carbolithiation of alkynes. It is shown that the presence of a lithium-chelating propargylic substituent completely reverses the otherwise favored syn-pro

Pd-catalyzed intramolecular acylation of aryl bromides via C-H functionalization: A highly efficient synthesis of benzocyclobutenones

Alvarez-Bercedo, Paula,Flores-Gaspar, Areli,Correa, Arkaitz,Martin, Ruben

supporting information; experimental part, p. 466 - 467 (2010/03/25)

(Chemical Equation Presented) A new catalyst system for the intramolecular acylation of aldehydes with aryl bromides via C-H functionalization is described. The transformation is distinguished by a remarkable functional group tolerance and hence allows fo
