1023565-25-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1023565-25-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,3,5,6 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1023565-25:
(9*1)+(8*0)+(7*2)+(6*3)+(5*5)+(4*6)+(3*5)+(2*2)+(1*5)=114
114 % 10 = 4
So 1023565-25-4 is a valid CAS Registry Number.

Copper-Catalyzed Cascade Synthesis of [1,2,4]-Triazoloquinazolinones

Lou, Zhenbang,Man, Ningning,Yang, Haijun,Zhu, Changjin,Fu, Hua

supporting information, p. 1395 - 1399 (2018/05/03)

An efficient and practical method for the synthesis of 1,2,4-triazolo[5,1- b ]quinazolin-9(3 H)-ones has been developed via the copper-catalyzed domino reactions of readily available substituted N ′-acetyl-2-bromobenzohydrazides with cyanamide. The protocol uses inexpensive CuI as the catalyst, and no other ligand or additive was required. The target products were prepared in good to excellent yields with tolerance of various functional groups.

An integration of condensation/Ullmann-type coupling/bicyclization sequences: Copper-catalyzed three-component direct synthesis of [1,2,4]triazolo[1,5-b]isoquinolin-5(1H)-ones

Jia, Feng-Cheng,Xu, Cheng,Cai, Qun,Wu, An-Xin

supporting information, p. 9914 - 9916 (2014/08/18)

A highly efficient three-component domino protocol has been developed for the synthesis of [1,2,4]triazolo[1,5-b]isoquinolin-5(1H)-ones from simple and readily available o-halogenated benzohydrazides, aldehydes and nitriles. This domino process involves sequential selective condensation, copper-catalyzed intermolecular C-arylation and bicyclization. Notably, the use of ligands and anaerobic conditions can be avoided in this reaction.
