Check Digit Verification of cas no

The CAS Registry Mumber 20051-06-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,0,5 and 1 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 20051-06:
(7*2)+(6*0)+(5*0)+(4*5)+(3*1)+(2*0)+(1*6)=43
43 % 10 = 3
So 20051-06-3 is a valid CAS Registry Number.

Metal-Free Photoinduced Transformation of Aryl Halides and Diketones into Aryl Ketones

Yao, Qiuli,Liu, Wenbo,Liu, Peng,Ren, Linjing,Fang, Xuehong,Li, Chao-Jun

supporting information, p. 2721 - 2724 (2019/01/14)

The acylation of aryl halides to prepare aryl ketones without metal catalyst represents an important yet challenging topic towards more sustainable ketone synthesis. Herein, we describe a simple and efficient metal-free protocol for the acylation of aryl halides with diketone under the irradiation of light utilizing N-methylpiperidine as base under an air atmosphere. This reaction can tolerate a wide range of functional groups and the corresponding ketones can be obtained in modest to good yields.

Ni-catalyzed activation of α-chloroesters: a simple method for the synthesis of α-arylesters and β-hydroxyesters

Durandetti, Muriel,Gosmini, Corinne,Périchon, Jacques

, p. 1146 - 1153 (2007/10/03)

Coupling reactions of α-chloroesters with aryl halides (α-arylation) or carbonyl compounds (Reformatsky) using nickel catalyst allow, under mild conditions, the preparation of various functionalized aryl propionic acid derivatives or β-hydroxyesters. In the synthesis of aryl propionic acid derivatives, the process is efficient with aryl halides bearing either electron-withdrawing or electron-donating groups.
