203442-83-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 203442-83-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,4,4 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 203442-83:
(8*2)+(7*0)+(6*3)+(5*4)+(4*4)+(3*2)+(2*8)+(1*3)=95
95 % 10 = 5
So 203442-83-5 is a valid CAS Registry Number.

Rhoda-Electrocatalyzed Bimetallic C?H Oxygenation by Weak O-Coordination

Tan, Xuefeng,Massignan, Leonardo,Hou, Xiaoyan,Frey, Johanna,Oliveira, Jo?o C. A.,Hussain, Masoom Nasiha,Ackermann, Lutz

supporting information, p. 13264 - 13270 (2021/05/06)

Rhodium-electrocatalyzed arene C?H oxygenation by weakly O-coordinating amides and ketones have been established by bimetallic electrocatalysis. Likewise, diverse dihydrooxazinones were selectively accessed by the judicious choice of current, enabling twofold C?H functionalization. Detailed mechanistic studies by experiment, mass spectroscopy and cyclovoltammetric analysis provided support for an unprecedented electrooxidation-induced C?H activation by a bimetallic rhodium catalysis manifold.

Fluoro-Substituted Methyllithium Chemistry: External Quenching Method Using Flow Microreactors

Colella, Marco,Degennaro, Leonardo,Higuma, Ryosuke,Ishikawa, Susumu,Luisi, Renzo,Nagaki, Aiichiro,Takahashi, Yusuke,Tota, Arianna

supporting information, p. 10924 - 10928 (2020/05/08)

The external quenching method based on flow microreactors allows the generation and use of short-lived fluoro-substituted methyllithium reagents, such as fluoromethyllithium, fluoroiodomethyllithium, and fluoroiodostannylmethyllithium. Highly chemoselective reactions have been developed, opening new opportunities in the synthesis of fluorinated molecules using fluorinated organometallics.

Broadly Applicable Ytterbium-Catalyzed Esterification, Hydrolysis, and Amidation of Imides

Guissart, Céline,Barros, Andre,Rosa Barata, Luis,Evano, Gwilherm

supporting information, p. 5098 - 5102 (2018/09/13)

An efficient, broadly applicable, operationally simple, and divergent process for the transformation of imides into a range of carboxylic acid derivatives under mild conditions is reported. By simply using catalytic amounts of ytterbium(III) triflate as a Lewis acid promoter in the presence of alcohols, water, amines, or N,O-dimethylhydroxylamine, a broad range of imides is smoothly and readily converted to the corresponding esters, carboxylic acids, amides, and Weinreb amides in good yields. This method notably enables an easy cleavage of oxazolidinone-based auxiliaries.
