54683-91-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 54683-91-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,6,8 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 54683-91:
(7*5)+(6*4)+(5*6)+(4*8)+(3*3)+(2*9)+(1*1)=149
149 % 10 = 9
So 54683-91-9 is a valid CAS Registry Number.

Synthesis, biological evaluation and molecular dynamics studies of oxadiazine derivatives as potential anti-hepatotoxic agents

Ahmed, Bahar,Akbar, Saleem,Das, Subham,Iqubal, Ashif

, (2021/07/06)

Generally, herbal medicines having remarkable popularity for treating liver ailments, but they are still unacceptable because of the deprivation of herbal drug standardization. Therefore, there is a need for promising synthetic drugs to overcome the criti

Nickel-Catalyzed Cross-Coupling of Aryl Redoxactive Esters with Aryl Zinc Reagents

Shih, Bo-Hao,Basha, R. Sidick,Lee, Chin Fa

, p. 8862 - 8866 (2019/09/30)

A nickel-catalyzed aryl-aroyloxyl C(sp2)-O radical cross-coupling reaction conducted using a redox active ester with aryl zinc reagent was developed. This method demonstrates a new disconnection approach for formation of aryl aryl esters. In the one-pot sequential process, the readily available aryl carboxylic acids can be converted into functionalized aryl aryl esters and heteroaryl esters. This protocol is amenable to the gram-scale synthesis. The present method has a wide substrate scope and high functional group tolerance.

Solid-Phase Benzoylation of Phenols and Alcohols in Microwave Reactor: An Ecofriendly Protocol

Chakraborty, Suchandra,Saha, Ahana,Basu, Kaushik,Saha, Chandan

supporting information, p. 2331 - 2343 (2015/10/12)

An efficient solid-phase benzoylation of phenols and alcohols was developed under microwave irradiation. A stoichiometric amount of benzoyl chloride was sufficient to carry out the reaction. This benzoylation features short reaction time, good yields, and easy workup procedures. Furthermore, the scope of the reaction was extended to prepare 3,5-dinitrobenzoyl derivatives of alcohols.
