Check Digit Verification of cas no

The CAS Registry Mumber 19552-08-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,5,5 and 2 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 19552-08:
(7*1)+(6*9)+(5*5)+(4*5)+(3*2)+(2*0)+(1*8)=120
120 % 10 = 0
So 19552-08-0 is a valid CAS Registry Number.

Wake promoting agents: Search for next generation modafinil, lessons learned: Part III

Dunn, Derek,Hostetler, Greg,Iqbal, Mohamed,Marcy, Val R.,Lin, Yin Guo,Jones, Bruce,Aimone, Lisa D.,Gruner, John,Ator, Mark A.,Bacon, Edward R.,Chatterjee, Sankar

, p. 3751 - 3753 (2012)

In searching for a next generation molecule to the novel wake promoting agent modafinil (compound 1), a series of fluorene-derived wakefulness enhancing agents were developed and evaluated in rat. Extensive pharmacokinetic studies of a potent member of the series (compound 15) revealed that the wake promotion activity of the analog was likely due to an active metabolite (compound 3).

Synthesis and conformational study of 1,1'-ethano-9,9'-bifluorenyl. Anti and Gauche conformers of a 9,9'-bifluorenyl derivative and chair and twist conformers of a dibenzo-1,5-cyclooctadiene derivative

Lai,Lee,Lee,Yi

, p. 2437 - 2446 (1993)

A Hofmann-type elimination of the sulphonium salt (18) under basic conditions led to the formation of a novel o-xylylene derivative (11) which dimerized regioselectively to give the bifluorenyl/dibenzo-1,5-cyclooctadiene derivative (3). The reaction is shown to be kinetically controlled and non-concerted. The two rigid conformers (3a) and (3b) were characterised by their 1H NMR spectra and they represent respectively the first observed examples of an anti bifluorenyl derivative and a twist dibenzo-1,5-cyclooctadiene derivative. A semiempirical molecular orbital PM3 calculation supported the observed results. Dynamic 1H NMR studies indicated an interconversion process (3a) ? (3b) at higher temperatures involving a conformational barrier estimated at 65.2 kJ mol-1.

Design and synthesis of 9H-fluorenone based 1,2,3-triazole analogues as Mycobacterium tuberculosis InhA inhibitors

Suresh, Amaroju,Srinivasarao, Singireddi,Agnieszka, Napiórkowska,Ewa, Augustynowicz-Kope?,Alvala, Mallika,Lherbet, Christian,Chandra Sekhar, Kondapalli Venkata Gowri

, p. 1078 - 1086 (2018/03/21)

We prepared fifty various 9H-fluorenone based 1,2,3-triazole analogues varied with NH, –S–, and –SO2– groups using click chemistry. The target compounds were characterized by routine analytical techniques, 1H, 13CNMR, mass, elemental, single-crystal XRD (8a) and screened for in vitro antitubercular activity against Mycobacterium tuberculosis (MTB) H37Rv strain and two “wild” strains Spec. 210 and Spec. 192 and MIC50 was determined. Further, the compounds were evaluated for MTB InhA inhibition study as well. The final analogues exhibited minimum inhibitory concentration (MIC) ranging from 52.35 to >295?μm. Among the –NH– analogues, one compound 5p (MIC 58.34?μm), among –S– containing analogues four compounds 8e (MIC 66.94?μm), 8f (MIC 74.20?μm), 8g (MIC 57.55?μm), and 8q (MIC 56.11?μm), among –SO2– containing compounds one compound 10p (MIC 52.35?μm) showed less than MTB MIC 74.20?μm: Compound 4-(((9H-fluoren-9-yl)sulfonyl)methyl)-1-(3,4,5-trimethoxyphenyl)-1H-1,2,3-triazole (10p) was found to be the most active compound with 73% InhA inhibition at 50?μm; it inhibited MTB with MIC 52.35?μm. Further, 10f and 10p were docked to crystal structure of InhA to know binding interaction pattern. Most active compounds were found to be non-cytotoxic against HEK 293 cell lines at 50?μm.

Equilibrium Acidities of Nitroalkanes in an Ionic Liquid

Gao, Feixiang,Ji, Pengju,Cheng, Jin-Pei

supporting information, p. 14962 - 14968 (2019/01/03)

The acidity ladder scale in [BMPY][NTf2] was successfully expanded toward the weak acidity region for about five more pK units compared to the previously established one. This allows the acidities of a series of 13 aliphatic and aromatic nitroalkanes to be determined accurately by the UV-vis spectroscopic method. The acidity of nitroalkane in [BMPY][NTf2] covers ~8 pK units and is significantly weaker than those in DMSO and water. The Hammett plot for 4-substituted phenylnitromethanes shows an excellent linearity with a slope of 2.06, which is rather close to that in DMSO but significantly larger than that in water (0.80). The regression analyses reveal that the solvation behavior of [BMPY][NTf2] on the acidic dissociations of C-H acids is similar to that of DMSO.

Efficient Solar-Driven Hydrogen Transfer by Bismuth-Based Photocatalyst with Engineered Basic Sites

Dai, Yitao,Li, Chao,Shen, Yanbin,Zhu, Shujie,Hvid, Mathias S.,Wu, Lai-Chin,Skibsted, J?rgen,Li, Yongwang,Niemantsverdriet, J. W. Hans,Besenbacher, Flemming,Lock, Nina,Su, Ren

supporting information, p. 16711 - 16719 (2018/12/11)

Photocatalytic organic conversions involving a hydrogen transfer (HT) step have attracted much attention, but the efficiency and selectivity under visible light irradiation still needs to be significantly enhanced. Here we have developed a noble metal-free, basic-site engineered bismuth oxybromide [Bi24O31Br10(OH)] that can accelerate the photocatalytic HT step in both reduction and oxidation reactions, i.e., nitrobenzene to azo/azoxybenzene, quinones to quinols, thiones to thiols, and alcohols to ketones under visible light irradiation and ambient conditions. Remarkably, quantum efficiencies of 42% and 32% for the nitrobenzene reduction can be reached under 410 and 450 nm irradiation, respectively. The Bi24O31Br10(OH) photocatalyst also exhibits excellent performance in up-scaling and stability under visible light and even solar irradiation, revealing economic potential for industrial applications.

A simple one-pot reaction between alcohols and 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane 2,4-disulfide (Lawesson's reagent, LR) affords the corresponding thiols, accompanied by dehydration products, alkenes.Treatment of acyclic 1,4-diols with LR gives the 1,3-dienes. o-(Dihydroxymethyl)benzene derivatives yield the 1,3-dihydrobenzothiophenes when treated with LR.
