Check Digit Verification of cas no

The CAS Registry Mumber 31202-23-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,2,0 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 31202-23:
(7*3)+(6*1)+(5*2)+(4*0)+(3*2)+(2*2)+(1*3)=50
50 % 10 = 0
So 31202-23-0 is a valid CAS Registry Number.

O-arylation versus C-arylation: Copper-catalyzed intramolecular coupling of aryl bromides with 1,3-dicarbonyls

Fang, Yewen,Li, Chaozhong

, p. 6427 - 6431 (2006)

The copper-catalyzed intramolecular coupling of aryl bromides with 1,3-dicarbonyls via a six-membered ring closure was examined. With CuI (10 mol %) as the catalyst, N,N′-dimethylethylenediamine as the ligand, and Cs2CO3 as the base,

Selective synthesis of 1-, and 3-carbomethoxy 2-tetralol stereoisomers by microbial reduction of the corresponding tetralones

Abalain, Cecile,Buisson, Didier,Azerad, Robert

, p. 2983 - 2996 (1996)

The microbial reduction of β-ketoesters derived from 2-tetralone has been shown to produce good yields of 2-hydroxy-1-carboxy- or 3-hydroxy-2-carboxyesters. Baker's yeast invariably affords a high enantiomeric purity cis-hydroxyester, while fungi strains may produce, sometimes exclusively, cis- or trans- complementary stereochemistries. From a general survey of the baker's yeast reduction of cyclic β-ketoesters, a working model for predicting enantio- and diastereoselectivities of the reduction is proposed and discussed.

2,4-Diaminopyrimidines as dual ligands at the histamine H1 and H4 receptor - H1/H4-receptor selectivity

Hammer, Sebastian G.,Gobleder, Susanne,Naporra, Franziska,Wittmann, Hans-Joachim,Elz, Sigurd,Heinrich, Markus R.,Strasser, Andrea

supporting information, p. 292 - 300 (2016/01/09)

Distinct diaminopyrimidines, for example, 4-(4-methylpiperazin-1-yl)-5,6-dihydrobenzo[h]quinazolin-2-amine are histamine H4 receptor (H4R) antagonists and show high affinity to the H4R, but only a moderate affinity to the

Mechanistic studies on the CAN-mediated intramolecular cyclization of δ-aryl-β-dicarbonyl compounds

Casey, Brian M.,Sadasivam, Dhandapani V.,Flowers II, Robert A.

, p. 1472 - 1479 (2013/08/23)

The synthesis of 2-tetralones through the cyclization of δ-aryl-β-dicarbonyl substrates by using CAN is described. Appropriately functionalized aromatic substrates undergo intramolecular cyclizations generating 2-tetralone derivatives in moderate to good yields. DFT computational studies indicate that successful formation of 2-tetralones from δ-aryl-β-dicarbonyl radicals is dependent on the stability of the subsequent cyclohexadienyl radical intermediates. Furthermore, DFT computational studies were used to rationalize the observed site selectivity in the 2-tetralone products.

Palladium catalysed bis- and tris-cyclisations furnishing fused cyclopropyl carbo/heterocycles

Grigg, Ronald,Sakee, Uthai,Sridharan, Visuvanathar,Sukirthalingam, Sukanthini,Thangavelauthum, Ravishanker

, p. 9523 - 9532 (2007/10/03)

Catalytic bis- and tris-cyclisation of a series of acyclic carbo- and heterocyclic precursors results in formation of two or three rings, two or three C-C bonds and two asymmetric tetrasubstituted C-centres regio- and stereoselectively in excellent yield.

cis- and trans-N-benzyl-octahydrobenzo[g]quinolines. Adrenergic and dopaminergic activity studies

Thermos, Kyriaki,Froudakis, George E.,Tagmatarchis, Nikos,Katerinopoulos, Haralambos E

, p. 883 - 886 (2007/10/03)

In vitro assays on a series of cis- and trans-octahydrobenzo[g]quinolines indicated an unusual trend of affinities at the dopaminergic receptors and α adrenoceptors. The trans N-benzyl analogues exhibited affinity at the α2 as well as the D1-like receptors whereas their N-unsubstituted congeners showed a distinct preference for the α2 adrenoceptor. Enhanced activity for the α2 receptors was also exhibited by the cis N-benzylated isomers. These observations are interpreted by theoretical calculations.

Asymmetric palladium annulation: Formal synthesis of (+)-huperzine A

Chassaing, Christophe,Haudrechy, Arnaud,Langlois, Yves

, p. 8805 - 8809 (2007/10/03)

A new formal stereoselective synthesis of (+)-huperzine A 1 was achieved using as a key step a palladium mediated annulation between 2-methylene-1,3- propanediol diacetate and (1R,2S)-2-phenylcyclohexanol derived β-ketoester 14.

A diastereoselective synthesis of trans/cis octahydronaphthoquinolizine

The tetracyclic system of 2,3,6,7,7a,8,12b,12c-octahydro-1H,5H-naphtho[1,2,3,i,j]quinolizine with trans/cis fusions of the B/D and B/C rings has been diastereospecifically synthesized in nine steps and in 23% total yield.
