Check Digit Verification of cas no

The CAS Registry Mumber 15864-32-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,8,6 and 4 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 15864-32:
(7*1)+(6*5)+(5*8)+(4*6)+(3*4)+(2*3)+(1*2)=121
121 % 10 = 1
So 15864-32-1 is a valid CAS Registry Number.

Synthesis of Indane-Based 1,5-Benzothiazepines Derived from 3-Phenyl-2,3-dihydro-1H-inden-1-one and Antimicrobial Studies Thereof

Mor, Satbir,Nagoria, Savita,Sindhu, Suchita,Khatri, Mohini,Sidhu, Gurdeep,Singh, Virender

, p. 3282 - 3293 (2017)

In the present study, a series of 20 indane-based 1,5-benzothiazepines (5a–t) has been prepared derived from 3-phenyl-2,3-dihydro-1H-inden-1-one (1). All the synthesized 1,5-benzothiazepines (5a–t) were screened for their in vitro antimicrobial activities against four bacteria [Bacillus subtilis (MTCC 441), Staphylococcus epidermidis (MTCC 6880), Escherichia coli (MTCC 1652), and Pseudomonas aeruginosa (MTCC 424)] and two fungi [Candida albicans (MTCC 227) and Aspergillus niger (MTCC 8189)]. Among all the tested derivatives, 5n and 5o against E.?coli displayed more inhibitory activity than that of the reference drug, ciprofloxacin, while the derivatives 5c, 5m–o, 5s, and 5t against C.?albicans, and 5d, 5e, 5n, 5o, 5s, and 5t against A.?niger were found to be more potent than the standard drug, that is, fluconazole.

, p. 1969 - 1987 (2017)

Abstract: Novel analogs of 3-(4-substituted benzylideneamino)-N-(6-substituted-1,3-benzo[d]thiazol-2-yl)-4,5-dihydro-5-oxo-pyrazole-1-carboxamide (5a–s) were designed and synthesized by reacting 3-amino-N-(6-substituted-1,3-benzo[d]thiazol-2-yl)-4,5-dihydro-5-oxo-pyrazole-1-carboxamide (4a–d) with p-substituted benzaldehydes. The Infrared Spectroscopy, 1H-Nuclear Magnetic Resonance, 13C-Nuclear Magnetic Resonance, and High Resolution Mass Spectra spectral data confirmed the structures of all the novel synthesized compounds. Among the series tested, two compounds 5k and 5o displayed promising antibacterial activity especially against Staphylococcus aureus (MIC = 3.14 and 1.57 μg/mL) and Bacillus subtilis (MIC = 3.12 and 1.84 μg/mL) respectively. Further, these title compounds were also assessed for their cytotoxic activity (IC50) against mammalian Vero cell line using 3-(4,5-dimethylthiazo-2-yl)-2,5-diphenyl-tetrazolium bromide assay, indicating that the compounds exhibit antibacterial activity at non-cytotoxic concentrations. Field based three-dimensional quantitative structure–activity relationships were also discussed based on the antimicrobial screening data. Graphical Abstract: Synthesis, spectral studies, antibacterial evaluation and QSAR studies of nineteen novel Schiff bases of pyrazol-5-one derivatives derived from 2-aminobenzothiazole nucleus are described.

Zhu, Yu-Shen,Shi, Linlin,Fu, Lianrong,Chen, Xiran,Zhu, Xinju,Hao, Xin-Qi,Song, Mao-Ping

supporting information, p. 1497 - 1500 (2021/09/09)

A facile and sustainable approach for the amination of benzothiazoles with KSeCN using iodine as the catalyst in water has been disclosed under transition-metal free conditions. The reaction proceeded smoothly to afford various primary 2-amino benzothiazoles in up to 96% yield. A series of control experiments were performed, suggesting a ring-opening mechanism was involved via a radical process. This protocol provides efficient synthesis of primary 2-aminobenzothiazoles

Shulga,Simurova,Shulga

, p. 364 - 368 (2021/04/13)

Abstract: The condensation of 2-amino-1,3-thiazolium perchlorates and their benzo analogs with trifluoro-acetyl-acetone in acetic acid afforded the corresponding [1,3]thiazolo[3,2-a]pyrimidinium, pyrimido[2,1-b][1,3]benzothiazolium, and naphtho[2′,1′:4,5][1,3]thiazolo[3,2-a]pyrimidinium salts as a single isomer in which the trifluoromethyl group is located in the γ-position with respect to the bridgehead nitrogen atom. The structure of the synthesized compounds was confirmed by 1H NMR spectra and elemental analyses.

Chemical Genetics Reveals a Role of Squalene Synthase in TGFβ Signaling and Cardiomyogenesis

Takemoto, Yasushi,Kadota, Shin,Minami, Itsunari,Otsuka, Shinya,Okuda, Satoshi,Abo, Masahiro,Punzalan, Louvy Lynn,Shen, Yan,Shiba, Yuji,Uesugi, Motonari

supporting information, p. 21824 - 21831 (2021/08/30)

KY02111 is a widely used small molecule that boosts cardiomyogenesis of the mesoderm cells derived from pluripotent stem cells, yet its molecular mechanism of action remains elusive. The present study resolves the initially perplexing effects of KY02111 on Wnt signaling and subsequently identifies squalene synthase (SQS) as a molecular target of KY02111 and its optimized version, KY-I. By disrupting the interaction of SQS with cardiac ER-membrane protein TMEM43, KY02111 impairs TGFβ signaling, but not Wnt signaling, and thereby recapitulates the clinical mutation of TMEM43 that causes arrhythmogenic right ventricular cardiomyopathy (ARVC), an inherited heart disease that involves a substitution of myocardium with fatty tissue. These findings reveal a heretofore undescribed role of SQS in TGFβ signaling and cardiomyogenesis. KY02111 may find its use in ARVC modeling as well as serve as a chemical tool for studying TGFβ/SMAD signaling.

Visible-light photoredox catalytic approach for the direct synthesis of 2-aminobenzothiazoles from anilines

Dhar S. Yadav, Lal,Krishna Pal Singh, Rana,Singh, Manjula

, (2020/02/13)

A novel, highly efficient and convenient approach for the visible-light-promoted direct synthesis of 2-aminobenzothiazoles from anilines and ammonium thiocyanate is presented. The reaction involves addition/cyclization cascade of SCN radical and anilines under photoredox catalysis with Ru(bpy)3Cl2. The salient features of the protocol include the utilization of atmospheric oxygen and visible light as clean, inexpensive and sustainable resources at room temperature.

ARS-TiO2 photocatalyzed direct functionalization of sp2 C-H bonds toward thiocyanation and cyclization reactions under visible light

Hosseini-Sarvari, Mona,Hosseinpour, Zeinab,Koohgard, Mehdi,Sarvestani, Abdollah Masoudi

, p. 1401 - 1407 (2020/03/26)

An ARS-TiO2 photocatalyst has been prepared, by a simple method through stirring a mixture of ARS and TiO2 at room temperature in the dark, to extend the photocatalytic response of titanium dioxide toward the visible light spectrum. The synergic effect of ARS and TiO2 in the photocatalyst system has catalyzed direct C-H functionalization of sp2 C-H bonds toward thiocyanation and cyclization reactions. Several aromatic and heteroaromatic scaffolds (2-phenylamino-thiazole, phenol, aniline, indole and pyrrole derivatives) were treated with the thiocyanate anion at room temperature. Herein, the first report on thiocyanation of phenol and synthesis of 2-aminobenzothiazole derivatives under visible light is presented.
