Check Digit Verification of cas no

The CAS Registry Mumber 20689-02-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,6,8 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20689-02:
(7*2)+(6*0)+(5*6)+(4*8)+(3*9)+(2*0)+(1*2)=105
105 % 10 = 5
So 20689-02-5 is a valid CAS Registry Number.

Design, synthesis and pharmacological evaluation of omeprazole-like agents with anti-inflammatory activity

El-Nezhawy, Ahmed O.H.,Biuomy, Ayman R.,Hassan, Fatma S.,Ismaiel, Ayman K.,Omar, Hany A.

, p. 1661 - 1670 (2013/05/09)

A new series of novel benzimidazole derivatives containing substituted pyrid-2-yl moiety and polyhydroxy sugar conjugated to the N-benzimidazole moiety has been synthesized and evaluated as orally bioavailable anti-inflammatory agents with anti-ulcerogenic activity. The anti-inflammatory and anti-ulcerogenic activities of these compounds were compared to diclofenac and omeprazole, respectively. In carrageenan-induced paw oedema assay, 2-methyl-N-((3,4-dimethoxypyridin-2-yl)methyl)-1H-benzimidazol-5-amine (12d) and 1-(1,2,3,5-tetrahydroxy-α-d-mannofuranose)-5-(((3,4-dimethoxypyridin-2yl) methyl)amino)-2-methyl-1H-benzimidazole (15d) displayed dose-dependent anti-inflammatory activities by decreasing the inflammation by 62% and 72%, respectively which is comparable to that of diclofenac (73%). In contrast to diclofenac, the anti-inflammatory activity of these compounds was not only free from any side effects on the gastric mucosa but also showed significant anti-ulcerogenic activity in rat pyloric ligation and ethanol-induced gastric ulcer models similar to that of omeprazole. Together, these findings suggest that 12d and 15d are potent anti-inflammatory agents with concurrent anti-ulcerogenic activity and support its clinical promise as a component of therapeutic strategies for inflammation, for which the gastric side effects are always a major limitation.

Double reductive amination and selective strecker reaction of a D-lyxaric aldehyde: Synthesis of diversely functionalized 3,4,5-trihydroxypiperidines

Matassini, Camilla,Mirabella, Stefania,Goti, Andrea,Cardona, Francesca

, p. 3920 - 3924 (2012/09/08)

A D-mannose-derived aldehyde with the D-lyxo configuration is a versatile key intermediate to functionally and stereochemically diversified piperidines. It allowed the synthesis of natural 3,4,5-trihydroxypiperidines and new analogs through a double reductive amination strategy and the synthesis of novel 2-cyanotrihydroxypiperidines through a highly regio-and diastereoselective Strecker reaction.

Chemoenzymatic synthesis of C8-modified sialic acids and related α2-3- and α2-6-linked sialosides

Naturally occurring 8-O-methylated sialic acids, including 8-O-methyl-N-acetylneuraminic acid and 8-O-methyl-N-glycolylneuraminic acid, along with 8-O-methyl-2-keto-3-deoxy-d-glycero-d-galacto-nonulosonic acid (Kdn8Me) and 8-deoxy-Kdn were synthesized fro

Stereoselective syntheses of polyhydroxylated azepane derivatives from sugar-based epoxyamides. Part 1: Synthesis from d-mannose

Ona, Noe,Romero, Antonio,Assiego, Carmen,Bello, Claudia,Vogel, Pierre,Pino-Gonzalez, M. Soledad

experimental part, p. 2092 - 2099 (2010/12/20)

An approach to the synthesis of polyhydroxyazepane derivatives from sugar-based epoxyamides or epoxyalcohols, in which the total regioselective epoxide opening by nitrogen nucleophiles is the key step, is described. Thus, novel polyhydroxyazepane carboxamides and aminomethyl polyhydroxyazepanes, with potential pharmacological interest, are synthesized from diacetone d-mannose. Configurational assignments of the obtained products were determined.
