Check Digit Verification of cas no

The CAS Registry Mumber 146744-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,7,4 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 146744-40:
(8*1)+(7*4)+(6*6)+(5*7)+(4*4)+(3*4)+(2*4)+(1*0)=143
143 % 10 = 3
So 146744-40-3 is a valid CAS Registry Number.

Activity and specificity studies of the new thermostable esterase EstDZ2

Myrtollari, Kamela,Katsoulakis, Nikolaos,Zarafeta, Dimitra,Pavlidis, Ioannis V.,Skretas, Georgios,Smonou, Ioulia

, (2020/09/16)

In this paper, we study the activity and specificity of EstDZ2, a new thermostable carboxyl esterase of unknown function, which was isolated from a metagenome library from a Russian hot spring. The biocatalytic reaction employing EstDZ2 proved to be an efficient method for the hydrolysis of aryl p-, o- or m-substituted esters of butyric acid and esters of secondary alcohols. Docking studies revealed structural features of the enzyme that led to activity differences among the different substrates.

Synthesis of o-nitrosoacylbenzenes from o-nitrobenzyl alcohols and their derivatives

Gazzaeva,Fedotov,Trofimova,Popova,Mochalov,Zefirov

, p. 87 - 99 (2007/10/03)

Nitration of substituted benzyl alcohols, as well as ethers and esters derived therefrom, with nitric acid in acetic anhydride was studied. The corresponding o-nitrobenzyl alcohols and their derivatives formed as the primary products are capable of being converted into o-nitrosoacylbenzenes by the action of acids.
