Check Digit Verification of cas no

The CAS Registry Mumber 39095-38-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,0,9 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 39095-38:
(7*3)+(6*9)+(5*0)+(4*9)+(3*5)+(2*3)+(1*8)=140
140 % 10 = 0
So 39095-38-0 is a valid CAS Registry Number.

Synthesis and insecticidal activity of spinosyn analogs functionally altered at the 2'-, 3'- and 4'-positions of the rhamnose moiety

Creemer, Lawrence C.,Kirst, Herbert A.,Paschal, Jonathan W.,Worden, Thomas V.

, p. 171 - 178 (2000)

In an effort to increase the insecticidal activity of the spinosyn family of naturally occurring macrolides, the 2'-, 3'- and 4'-O-desmethyl-O-acetyl analogs and the 2'-, 3'-, and 4'-O-desmethoxy analogs have been synthesized. These analogs were prepared synthetically from the minor spinosyn factors H, J, K, L and Q either via direct acylation of the corresponding factor or deoxygenation of an intermediate xanthate. The acylated analogs were all more potent insecticides against Heliothis virescens larvae than their respective parent factors, but not as potent as spinosyns A or D. The deoxy analogs were also more potent insecticides than their respective parent factors. The 2'-desmethoxy analogs showed, for the first time, analogs with insecticidal potency against H. virescens greater than that of spinosyns A and D, indicating that polarity is not well tolerated in the rhamnose moiety of spinosyn A.

Page/Page column 64, (2010/04/23)

Compounds useful as antibacterial agents are provided. The compounds are analogs of indole-3-carbinol and have a backbone selected from dihydroindolo[2,3-b]carbazole, 2,2'-diindolylmethane, 2',3-diindolylmethane, and 3,3'-diindolylmethane. The compounds are useful therapeutic and prophylactic treatment of bacterial infections in mammals. Methods of synthesis of the compounds are provided, as are pharmaceutical compositions containing the compounds.

Synthesis of 1-hydroxybicyclo[3.2.1]oct-3-en-2-ones by Acyloin rearrangement of 1-methoxy- or 1-tert-butyldimethylsilyloxybicyclo [2.2.2] oct-5-en-2-ones

, p. 1419 - 1427 (2007/10/03)

1-Hydroxy-or 1,8-dihydroxy-bicyclo[3,2,1]oct-3-en-2-ones were obtained from 1-methoxy- or 1-tert-butyldimethylsilyloxy-bicyclo[2,2,2]oct-5-en-2- ones via successive processes involving demethylation or desilylation and acyloin rearrangement by reaction wi

3-Unsubstituted 1,5-diaryl-2,4-pentanediones and -4-methoxy-2-pentanones: Synthesis via corresponding 3-hydroxy ketones generated from 2-isoxazolines

Pulkkinen, Juha T.,Vepsaelaeinen, Jouko J.

, p. 8604 - 8609 (2007/10/03)

Aryl acetaldoximes are reacted with allylarenes in the presence of sodium hypochlorite to give 3,5-bis(arylmethyl)-2-isoxazolines which are then converted to 1,5-diaryl-4-hydroxy-2-pentanones by a reductive hydrogenation in the presence of water. These in

Donor substituted sulfonyl carbenes, 2: Organothio sulfonyl carbenes

Schank, Kurt,Abdel Wahab, Aboel-Magd A.,Buegler, Stephan,Eigen, Peter,Jager, Juergen,Jost, Klaus

, p. 3721 - 3742 (2007/10/02)

Organothio sulfonyl carbenes 3 have been generated via ylid thermolysis or via α-elimination starting from α-chloro α-organothio sulfones and their derivatives. They have been captured by suitable nucleophilic trapping reagents (diazomethane, enol ethers, and other). Their nucleophilic carbenoid precursors could be trapped by an electrophilic olefin (ketene dithioacetal S,S-dioxides as Michael acceptors). Stable carbene Z-dimers could be obtained under various conditions. Bromine catalyzed isomerization to E-isomers proved to be reversible.

Convenient synthesis of 2,4-cyclohexadien-1-ones by regioselective methylthiomethylation of phenols

Convenient Synthesis of Sulfur Ylides by Reaction of Active Methylene Compounds with Corey-Kim Reagent

Katayama, Sadamu,Watanabe, Toshio,Yamauchi, Masashige

Reactions of active methylene compounds with Corey-Kim reagent in the presence of triethylamine afford stable sulfur ylides in satisfactory yields.

INDOLE- AND PYRROLE-SULFONIUM YLIDES

Hartke, Klaus,Teuber, Dorothee,Gerber, Hans-Dieter

, p. 3261 - 3270 (2007/10/02)

Electrophilic substitution of indole and pyrrole with sulfoxides and acid anhydrides leads to the formation of indole-3-sulfonium salts and pyrrole-2-sulfonium salts.These are deprotonated with potassium carbonate to give indole-3-sulfonium ylides and pyr

Synthesis of 1,3-Dicarbonyl Compounds by the Oxidation of 3-Hydroxycarbonyl Compounds with Corey-Kim Reagent

Katayama, Sadamu,Fukuda, Kinue,Watanabe, Toshio,Yamauchi, Masashige

, p. 178 - 183 (2007/10/02)

A new method for the preparation of various 1,3-dicarbonyl compounds is described.Oxidation of 3-hydroxycarbonyl compounds without substituent at C-2 position by the Corey-Kim reagent (N-chlorosuccinimide-dimethyl sulfide) afforded the stable dimethylsulfonium methylides, which on reductive desulfurization by zinc-acetic acid furnished the 1,3-dicarbonyl derivatives.On the other hand, the same treatment of 2-mono-, or 2,2-disubstituted 3-hydroxy-carbonyl compounds gave directly the corresponding 1,3-dicarbonyl analogous, respectively.
