154479-68-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 154479-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,4,7 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 154479-68:
(8*1)+(7*5)+(6*4)+(5*4)+(4*7)+(3*9)+(2*6)+(1*8)=162
162 % 10 = 2
So 154479-68-2 is a valid CAS Registry Number.

Copper-Catalyzed Decarboxylative Oxyalkylation of Alkynyl Carboxylic Acids: Synthesis of ?-Diketones and ?-Ketonitriles

Li, Yi,Shang, Jia-Qi,Wang, Xiang-Xiang,Xia, Wen-Jin,Yang, Tao,Xin, Yangchun,Li, Ya-Min

supporting information, p. 2227 - 2230 (2019/03/26)

A novel copper-catalyzed decarboxylative oxyalkylation of alkynyl carboxylic acids with ketones and alkylnitriles via direct C(sp3)-H bond functionalization to construct new C-C bonds and C-O double bonds was developed. This transformation is featured by wide functional group compatibility and the use of readily available reagents, thus affording a general approach to ?-diketones and ?-ketonitriles. A possible mechanism is proposed.

Polycondensed Nitrogen Heterocycles. Part 25. Aminopyrrolophenanthridines by Decomposition of 2-(3-Azidophenyl)-1-arylpyrroles

Almerico, Anna Maria,Cirrincione, Girolamo,Dattolo, Gaetano,Aiello, Enrico,Mingoia, Francesco

, p. 193 - 198 (2007/10/02)

Acid catalyzed decomposition of the azido derivatives 4a-c give rise to amino-hydroxy-phenylpyrroles of type 7 and 8 upon hydrolysis of the intermediate aryl nitrenium ions, together with the hydrogen abstraction compounds of type 3.The aminopyrrolo1,2-f
