80206-34-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 80206-34-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,2,0 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 80206-34:
(7*8)+(6*0)+(5*2)+(4*0)+(3*6)+(2*3)+(1*4)=94
94 % 10 = 4
So 80206-34-4 is a valid CAS Registry Number.

A sinter-resistant catalytic system based on platinum nanoparticles supported on TiO2 nanofibers and covered by porous silica

Dai, Yunqian,Lim, Byungkwon,Yang, Yong,Cobley, Claire M.,Li, Weiyang,Cho, Eun Chul,Grayson, Benjamin,Fanson, Paul T.,Campbell, Charles T.,Sun, Yueming,Xia, Younan

, p. 8165 - 8168 (2010)

Holey support: The generation of a porous coating of SiO2 on Pt-decorated TiO2 nanofibers enables the preparation of a sinter-resistant catalytic system (see picture). The Pt nanoparticles could resist sintering at temperatures up to 750C in air, as the SiO2 coating acts as a physical barrier that slows down surface migration, but the system remained catalytically active because of the porous nature of the coating.

Conjugation of tacrine with genipin derivative not only enhances effects on AChE but also leads to autophagy against Alzheimer's disease

Lin, Rongtian,Rao, Shuwen,Li, Yanbing,Zhang, Lei,Xu, Liyu,He, Yepu,Liu, Zhijun,Chen, Heru

, (2020/12/21)

Seven tacrine/CHR21 conjugates have been designed and synthesized. Compound 8-7 was confirmed as the most active AChE inhibitor with IC50 value of 5.8 ± 1.4 nM, which was 7.72-fold stronger than tacrine. It was also shown as a strong BuChE inhibitor (IC50 value of 3.7 ± 1.3 nM). 8-7 was clearly highlighted not only as an excellent ChEs inhibitor, but also as a good modulator on protein expression of AChE, p53, Bax, Bcl-2, LC3, p62, and ULK, indicating its functions against programmed cell apoptosis and decrease of autophagy. 8-7 significantly reversed the glutamate-induced dysfunctions including excessive calcium influx and release from internal organelles, overproduction of nitric oxide (NO) and Aβ high molecular weight oligomer. This compound can penetrate blood?brain barrier (BBB). The in vivo hepatotoxicity assay indicated that 8-7 was much less toxic than tacrine. Altogether, these data strongly support that 8-7 is a potential multitarget-directed ligand (MTDL) for treating Alzheimer's disease (AD).

A highly selective diarylethene fluorescence sensor of aluminum ion and its application

Fan, Congbin,Liu, Gang,Pu, Shouzhi,Wang, Huaxin,Zhao, Heng

, (2020/10/18)

A novel diarylethene derivative 1O with the unit of N-(2-(hydrazinecarbonyl)phenyl)benzamide was designed and synthesized successfully. The sensor showed excellent photochromism and specific fluorescent detection toward aluminum ion with rarely interfering. The emission intensity could increase nearly by 100 folds with aluminum ion and the color changed from dark to Aqua green. The low limit of detection (LOD) of 1O was determined as 3.26 × 10-8 mol L-1. Additionally, the sensor could be used in logic circuit and aluminum ion detection in untreated water.
