63203-39-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 63203-39-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,2,0 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 63203-39:
(7*6)+(6*3)+(5*2)+(4*0)+(3*3)+(2*3)+(1*9)=94
94 % 10 = 4
So 63203-39-4 is a valid CAS Registry Number.

Titanium-catalyzed stereoselective synthesis of spirooxindole oxazolines

Badillo, Joseph J.,Arevalo, Gary E.,Fettinger, James C.,Franz, Annaliese K.

, p. 418 - 421 (2011)

A regio-and stereoselective cyclization between isatins and 5-methoxyoxazoles has been developed using catalytic titanium (IV) chloride (10 or 20 mol %) to afford spiro[3,3'-oxindoleoxazolines] in excellent yield (up to 99%) and diastereoselectivity (dr >

Disclosed is a plant disease control agent comprising an amide compound represented by the formula (1) as an active ingredient. (1): wherein X1 represents a fluorine atom or a methoxy group; X2 represents a hydrogen atom, a halogen atom, a C1-C4 alkyl group, a C2-C4 alkenyl group, a C1-C4 haloalkyl group, a C1-C4 alkoxy group, a C1-C4 alkylthio group, a C1-C4 hydroxyalkyl group and so on; Z1 represents an oxygen atom or a sulfur atom; A1 represents a single bond, -CH2- and so on; and G1 represents a group CR6R7R8, a C3-6 cycloalkyl group and so on.

Cytosporone E: Racemic synthesis and preliminary antibacterial testing

Hall, Jeffrey D.,Duncan-Gould, Nathan W.,Siddiqi, Nasar A.,Kelly, Jennifer N.,Hoeferlin, L. Alexis,Morrison, Susan J.,Wyatt, Justin K.

, p. 1409 - 1413 (2007/10/03)

The antibiotic cytosporone E (isolated from the broth of the endophytic fungi CR 200 (Cytospora sp.) and CR 146 (Diaporthe sp.)) was synthesized as a racemic mixture. The key step in the synthesis is the Meyers ortho-alkylation of a chiral aromatic oxazoline. Preliminary antibiotic activity shows antibiosis against Gram-positive bacteria but not Gram-negative bacteria as previously reported.
