Check Digit Verification of cas no

The CAS Registry Mumber 34128-30-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,1,2 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 34128-30:
(7*3)+(6*4)+(5*1)+(4*2)+(3*8)+(2*3)+(1*0)=88
88 % 10 = 8
So 34128-30-8 is a valid CAS Registry Number.

Direct Carboxylation of Electron-Rich Heteroarenes Promoted by LiO-tBu with CsF and [18]Crown-6

Shigeno, Masanori,Hanasaka, Kazuya,Sasaki, Keita,Nozawa-Kumada, Kanako,Kondo, Yoshinori

supporting information, p. 3235 - 3239 (2019/02/13)

We herein demonstrate that the combination of LiO-tBu, CsF, and [18]crown-6 efficiently promotes the direct C?H carboxylation of electron-rich heteroarenes (benzothiophene, thiophene, benzofuran, and furan derivatives). A variety of functional groups, including methyl, methoxy, halo, cyano, amide, and keto moieties, are compatible with this system. The reaction proceeds via the formation of a tert-butyl carbonate species.

Supramolecular control of selectivity in hydroformylation of vinyl arenes: Easy access to valuable β-aldehyde intermediates

Dydio, Pawel,Reek, Joost N. H.

supporting information, p. 3878 - 3882 (2013/05/09)

Go against the flow! A rationally designed regioselective hydroformylation catalyst, [Rh/L], in which noncovalent ligand-substrate interactions allow the unprecedented reversal of selectivity from the typical α-aldehyde to the otherwise unfavored product β-aldehyde, is reported. This catalytic system opens up novel and sustainable synthetic pathways to important intermediates for the fine-chemicals industry.

, p. 7135 - 7139 (2013/01/15)

A concise and efficient approach to a series of chromen-4-ones with fused thiophene ring has been developed using the Suzuki-Miyaura reaction of bromothiophene-2- and 3-carboxylates with 2-methoxyboronic acids and subsequent cyclization of prepared alkyl (2-methoxy)aryl thiophene-2- and 3-carboxylates under the action of BBr3/KOtBu. Starting bromothiophenes are easily obtained from corresponding commercially available aminothiophenes by diazotization/bromination reaction.

HETEROCYCLIZATION OF ACETYLENE DERIVATIVES BY THE ACTION OF SULFUR DIOXIDE AND HYDROGEN BROMIDE

Zborovskii, Yu. L.,Smirnov-Zamkov, I. V.,Staninets, V. I.

, p. 1617 - 1625 (2007/10/02)

Under the influence of sulfur dioxide and hydrogen bromide acetylenes activated by strong electron-withdrawing substituents undergo oxidative-reductive heterocyclization, leading to the formation of heterocyclic systems containing sulfide sulfur.The hydrogen bromide acts as reducing agent in these processes.The released bromine oxidizes the excess of sulfur dioxide to sulfuric acid.The reaction takes place by a heterolytic donor-acceptor mechanism.The addition of hydrogen bromide and sulfur dioxide to the CC bond evidently gives sulfinic acids, which are thenreduced to sulfenyl bromides.In the case of phenylacetylene derivatives intramolecular cyclization of the sulfenyl bromides leads to the formation of benzothiophenes.The dicyanoacetylene and acetylenedicarboxamide are converted into the corresponding isothiazoles.The heterocyclization of two molecules of sulfenyl bromide leads to the formation of 1,4-dithiin derivatives.
