51145-18-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 51145-18-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,1,4 and 5 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 51145-18:
(7*5)+(6*1)+(5*1)+(4*4)+(3*5)+(2*1)+(1*8)=87
87 % 10 = 7
So 51145-18-7 is a valid CAS Registry Number.

Palladium-catalyzed decarboxylative ortho-acylation of N-nitrosoanilines with α-oxocarboxylic acids

Yao, Jia-Ping,Wang, Guan-Wu

, p. 1687 - 1690 (2016)

A palladium-catalyzed efficient C-H acylation reaction of N-nitrosoanilines with α-oxocarboxylic acids has been developed. The reaction proceeded smoothly with potassium persulfate as the oxidant to afford acylated N-nitrosoanilines in moderate to good yi

Palladium-catalyzed ortho-acylation of N-Nitrosoanilines with α-oxocarboxylic acids: A convenient method to synthesize N-Nitroso ketones and indazoles

Zhang, Liang,Wang, Zhe,Guo, Peiyu,Sun, Wei,Li, Ya-Min,Sun, Meng,Hua, Chengwen

, p. 2511 - 2514 (2016/05/24)

An efficient and mild protocol for regioselective synthesis of N-Nitroso aryl ketones by palladium-catalyzed direct acylation of arenes using N-Nitroso as directing groups is described. This reaction proceeded smoothly and could tolerate a variety of functional groups. Moreover, this chemistry offers a convenient access to a range of indazoles.
