Check Digit Verification of cas no

The CAS Registry Mumber 19820-51-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,2 and 0 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19820-51:
(7*1)+(6*9)+(5*8)+(4*2)+(3*0)+(2*5)+(1*1)=120
120 % 10 = 0
So 19820-51-0 is a valid CAS Registry Number.

2-formyl-3,6-bis(hydroxymethyl)phenyl benzoate in Electrochemical Dry Cell

Khan, Jamil,Muhammad, Bakhtiar,Shahida, Shabnam,Shah, Khizar Hussain,Irfan, Muhammad Imran,Ahmad, Tauqeer,Fahad, Muhammad

, p. 912 - 917 (2018)

Solvated organic compound with the general formula 2-formyl-3,6-bis(hydroxymethyl)phenyl benzoate [C16H14O5] was synthesized. Fourier-transform infrared (FTIR), Mass Spectrometry (MS) and X-ray powder analytical methods were used here for structure elucidation. Characterization revealed a triclinic geometry with space group P1. The refined unit cell parameters are, a = 15.196 ?, b = 14.882 ? and c = 14.606 ?. Development in present work is an idea of the organic electrochemical dry cell. Electrochemists with an idea in vitro/vivo development in present assay are openly encouraged for supporting exploration.

Copper-catalyzed chemoselective oxidative o-aroylation of 2-acetylphenols, alkyl salicylates and 1,3-dicarbonyl compounds using styrene derivatives

Kumar, Upendra,Sharma, Ajay,Kumar, Naveen,Pandey, Satyendra Kumar

, (2021/03/03)

A novel copper-catalyzed chemoselective oxidative O-aroylation of 2-acetylphenols, alkyl salicylates and 1,3-dicarbonyl compounds with a wide range of styrene derivatives are described. This approach provides an efficient chemoselective preparation of phenol, alkyl salicylate and enol esters in good to excellent yields. This method represents an alternative protocol for the classical esterification reactions.

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.
