Check Digit Verification of cas no

The CAS Registry Mumber 102-46-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 2 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 102-46:
(5*1)+(4*0)+(3*2)+(2*4)+(1*6)=25
25 % 10 = 5
So 102-46-5 is a valid CAS Registry Number.

Improved preparation of 3,3′,4,4′-tetramethyldiphenylethane by self coupling reaciton in aqueous media

Hu, Yu-Lin,Lu, Ming,Liu, Qi-Fa,Ge, Qiang

, p. 1056 - 1063 (2009)

In this article, 3,3′,4,4′-tetramethyldiphenylethane was obtained in 86.5% total yield by self coupling reaction of 3,4-dimethylbenzyl chloride catalyzed by Cu/Cu/2/Cl/2//PEG-600 and promoted by iron in aqueous media and the starting

A highly efficient synthetic method for the preparation of 3,4-dimethylbenzaldehyde from o-xylene in aqueous media

Hu,Lu,Liu,Wei,Liu

, p. 487 - 494 (2010)

In this study, 3,4-dimethylbenzaldehyde was obtained in 82.3% total yield by oxidation of 3,4-dimethylbenzyl chloride with NaNO3/AcOH catalyzed by PEG-600 in aqueous media. The starting material 3,4-dimethylbenzyl chloride was prepared by chloromethylation of o-xylene in CTAB micellar catalytic system. Compared with other synthetic methods, this method not only enhanced the yield, but also afforded an efficient work-up procedure. The structures of the products were confirmed by Elemental analysis,1H NMR and 13C NMR or compared with authentic samples.

Mechanism of solvolysis of substituted benzyl chlorides in aqueous ethanol

Denegri, Bernard,Mati?, Mirela,Va?ko, Monika

supporting information, (2021/11/22)

The mechanism of solvolyses of activated ortho-, meta- and para-substituted benzyl chlorides in aqueous ethanol has been studied by using the Hammett-Brown and Yukawa-Tsuno treatments as well as by correlating logarithms of solvolysis rate constants with relative stabilities of corresponding benzyl carbocations in water calculated at the IEFPCM-M06–2X/6-311+G(3df,3pd) level of theory. Benzyl chlorides containing strong conjugative electron-donors in the para-position solvolyze by the SN1 mechanism, whereas other activated benzyl chlorides solvolyze by the SN2 mechanism via loose transition states.

An experimental and theoretical study on imidazolium-based ionic liquid promoted chloromethylation of aromatic hydrocarbons

Wang, Yun,Xi, Yanli

, p. 2196 - 2199 (2014/03/21)

The chloromethylation of aromatic hydrocarbons proceeded efficiently using the reusable imidazolium-based ionic liquid as promoter. Mild reaction conditions, enhanced rates, improved yields, recyclability of ionic liquids, and reagents' reactivity which is different from that in conventional organic solvents are the remarkable features observed in ionic liquids. The ionic liquids were recycled in three subsequent runs with no decrease in activity. In addition, the results of calculations with the Gaussian 98 suite of program are in good accordance with the experimental outcomes.

Identification of alkylarene chloromethylation products using gas-chromatographic retention indices

Zenkevich,Makarov

, p. 611 - 619 (2008/03/18)

Gas-chromatographic retention indices on standard nonpolar polydimethylsiloxane stationary phases allow identification of products formed by known organic reactions even without using mass-spectrometric data. The efficiency of this approach was demonstrated by the example of identification of previously uncharacterized chloromethyl derivatives of alkylarenes, including structural isomers of compounds containing several chloromethyl groups, directly in reaction mixtures. Chromatographic analysis of such reaction mixtures allows identification of positional isomers of the starting alkylarenes even when they are present simultaneously. The retention indices were determined for the first time for more than 50 alkyl-(chloromethyl)arenes, by-products of chloromethylation, and chloromethyl derivatives of the simplest alkyl phenyl ketones.
