190840-85-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 190840-85-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,8,4 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 190840-85:
(8*1)+(7*9)+(6*0)+(5*8)+(4*4)+(3*0)+(2*8)+(1*5)=148
148 % 10 = 8
So 190840-85-8 is a valid CAS Registry Number.

Gold-Catalyzed Oxidation of Thioalkynes to Form Phenylthio Ketene Derivatives via a Noncarbene Route

Sharma, Pankaj,Singh, Rahulkumar Rajmani,Giri, Sovan Sundar,Chen, Liang-Yu,Cheng, Mu-Jeng,Liu, Rai-Shung

, p. 5475 - 5479 (2019/08/01)

Gold-catalyzed oxidations of thioalkynes with 8-methylquinoline oxides afford 2-phenylthioketenes that can be trapped efficiently with alcohols. The synthetic utility is manifested by terminal and internal thioalkynes over a wide scope, bearing esters, ke

Highly regioselective hydrosilylation of unsymmetric alkynes using a phenylthio directing group

Huang, Kuan-Hsun,Isobe, Minoru

, p. 4733 - 4740 (2014/08/05)

Cobalt-assisted hydrosilylation of acetylenes is particularly interesting in organic synthesis since alkynyl group functionalization can give way to more useful substructures. This study aims to answer the general question of how to control hydrosilylatio

An Expedient Route for the Stereoselective Construction of Bridged Polyheterocyclic Ring Systems Using the Tandem "Pincer" Diels-Alder Reaction

Lautens, Mark,Fillion, Eric

, p. 4418 - 4427 (2007/10/03)

The tandem "pincer" Diels-Alder reaction, consisting of two consecutive [4 + 2] cycloadditions between two dienes and an acetylenic bis-dienophile, has been applied toward the rapid construction of bridged polyoxacyclic ring systems when furan derivatives are used as the diene components. The study has demonstrated the stereoselectivity (exo-exo adduct), the chemoselectivity ("pincer" vs "domino"), as well as the regioselectivity of the reaction. The reaction has been successfully applied to a variety of 2-substituted furans and tethered bis-furans in combination with mono-activated and diactivated dienophiles. The synthesis of unsymmetrical cycloadducts starting from the aza- and oxanorbornadiene-type intermediate has also been realized.
