5497-43-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5497-43-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,9 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5497-43:
(6*5)+(5*4)+(4*9)+(3*7)+(2*4)+(1*3)=118
118 % 10 = 8
So 5497-43-8 is a valid CAS Registry Number.

Intriguing influence of the solvent on the regioselectivity of sulfoxide thermolysis in β-amino-α-sulfinyl esters

Baenziger, Markus,Klein, Solange,Rihs, Grety

, p. 1399 - 1406 (2007/10/03)

The sulfoxide thermolysis of the diastereoisomeric methyl (3R,4aS, 10aR)-6-methyl-3-methyl-3-(phenyl-sulfinyl)-1,2,3,4,4a,5,10,10a- octahydrobenzo[g]quinoline-3-carboxylates 3a and 3′b in toluene yields, by loss of benzenesulfenic acid, an almost 1:1 mixture of the vinylogous urethane 2b and the isomeric α-aminomethyl enoate 2a. When this elimination is performed in acetic acid, the enoate 2a is formed rather selectively. The same solvent effects on the regioselectivity of the elimination of benzenesulfenic acid are observed with a simple sulfoxide of ethyl piperidine-3-carboxylate (7).

Cholinergic agents: Effect of methyl substitution in a series of arecoline derivatives on binding to muscarinic acetylcholine receptors

Moos,Bergmeier,Coughenour,Davis,Hershenson,Kester,McKee,Marriott,Schwarz,Tecle,Thomas

, p. 1015 - 1019 (2007/10/02)

Arecoline, arecaidine, and a series of derivatives, differing by the presence or absence of methyl groups at positions on the periphery of the molecule, were prepared, and their binding to muscarinic acetylcholine receptors was tested. On the basis of this study, muscarinic agonism for arecoline series is governed by strict structure-activity relationships, as previously observed for other agonist series. Only minor changes in nitrogen substitution were tolerated in the present series of arecoline derivatives.

2-OXOTETRAHYDRO-1,3-OXAZINE : A USEFUL INTERMEDIATE FOR THE PREPARATION OF TETRAHYDROPYRIDINE, INDOLIZIDINE, AND QUINOLIZIDINE SKELETONS

Kurihara, Takushi,Matsubara, Yoshitaka,Osaki, Hirotaka,Harusawa, Shinya,Yoneda, Ryuji

, p. 885 - 896 (2007/10/02)

Conversion of 2-oxotetrahydro-1,3-oxazines into tetrahydropyridines was applied to the synthesis of indolizidine and quinolizidine alkaloids.
