Check Digit Verification of cas no

The CAS Registry Mumber 20277-02-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,7 and 7 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20277-02:
(7*2)+(6*0)+(5*2)+(4*7)+(3*7)+(2*0)+(1*2)=75
75 % 10 = 5
So 20277-02-5 is a valid CAS Registry Number.

Synthesis and biological evaluation of some new furoxan derivatives as anti-inflammatory agents

Amir, Mohd,Verma, Jeevan S.,Tariq, Sana,Somakala,Ehtaishamul Haq

, p. 955 - 959 (2019/05/21)

A new series of furoxan derivatives (3a-k) have been synthesized and characterized by their IR, 1H NMR and mass spectral data. All the compounds have been screened for their anti-inflammatory activity. The compounds 3a, 3b, 3f, 3g, and 3i which show significant anti-inflammatory activity have been further studied for their ulcerogenic activities and nitric oxide releasing properties. Furoxan derivative 3-memyl-4-[{2-(2-phenylacetyl)hydrazono}memyl]-furoxan 3f showed greater anti-inflammatory activity comparable to standard drug ibuprofen. The compound also showed reduced, ulcerogenicity and high nitric oxide releasing properties.

2,3,4-Trihydroxybenzyl-hydrazide analogues as novel potent coxsackievirus B3 3C protease inhibitors

Kim, Bo-Kyoung,Ko, Hyojin,Jeon, Eun-Seok,Ju, Eun-Seon,Jeong, Lak Shin,Kim, Yong-Chul

, p. 202 - 216 (2016/05/24)

Human coxsackievirus B3 (CVB3) 3C protease plays an essential role in the viral replication of CVB3, which is a non-enveloped and positive single-stranded RNA virus belonging to Picornaviridae family, causing acute viral myocarditis mainly in children. During optimization based on SAR studies of benserazide (3), which was reported as a novel anti-CVB3 3Cpro agent from a screening of compound libraries, the 2,3,4-trihydroxybenzyl moiety of 3 was identified as a key pharmacophore for inhibitory activity against CVB3 3Cpro. Further optimization was performed by the introduction of various aryl-alkyl substituted hydrazide moieties instead of the serine moiety of 3. Among the optimized compounds, 11Q, a 4-hydroxyphenylpentanehydrazide derivative, showed the most potent inhibitory activity (IC50 Combining double low line 0.07 μM). Enzyme kinetics studies indicated that 11Q exhibited a mixed inhibitory mechanism of action. The antiviral activity against CVB3 was confirmed using the further derived analogue (14b) with more cell permeable valeryl ester group at the 2,3,4-trihydroxy moiety.

Synthesis of 3-hydroxyindanones via potassium salt of amino acid catalyzed regioselective intramolecular aldolization of ortho-diacylbenzenes

Chanda, Tanmoy,Chowdhury, Sushobhan,Anand, Namrata,Koley, Suvajit,Gupta, Ashutosh,Singh, Maya Shankar

supporting information, p. 981 - 985 (2015/03/04)

First organocatalytic intramolecular aldolization of ortho-diacylbenzenes to construct highly functionalized 3-hydroxyindanones is described. In this transformation a high trans-selectivity is achieved by the use of metal salt of amino acid. This method allows an easy access to the strained spirocyclic 3-hydroxyindanones related to a number of natural product frameworks. Synthesis of a new class of indole skeleton substituted by 3-hydroxyindanones added an extra essence to this new protocol.
