Check Digit Verification of cas no

The CAS Registry Mumber 50671-05-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,6,7 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 50671-05:
(7*5)+(6*0)+(5*6)+(4*7)+(3*1)+(2*0)+(1*5)=101
101 % 10 = 1
So 50671-05-1 is a valid CAS Registry Number.

Synthesis of Dithiolethiones and Identification of Potential Neuroprotective Agents via Activation of Nrf2-Driven Antioxidant Enzymes

Bai, Feifei,Fang, Jianguo,Song, Zi-Long,Zhang, Baoxin

, p. 2214 - 2231 (2020/03/06)

Oxidative stress is implicated in the pathogenesis of a wide variety of neurodegenerative disorders, and accordingly, dietary supplement of exogenous antioxidants or/and upregulation of the endogenous antioxidant defense system are promising for therapeutic intervention or chemoprevention of neurodegenerative diseases. Nrf2, a master regulator of the cellular antioxidant machinery, cardinally participates in the transcription of cytoprotective genes against oxidative/electrophilic stresses. Herein, we report the synthesis of 59 structurally diverse dithiolethiones and evaluation of their neuroprotection against 6-hydroxydopamine-or H2O2-induced oxidative damages in PC12 cells, a neuron-like rat pheochromocytoma cell line. Initial screening identified compounds 10 and 11 having low cytotoxicity but conferring remarkable protection on PC12 cells from oxidative-mediated damages. Further studies demonstrated that both compounds upregulated a battery of antioxidant genes as well as corresponding genes' products. Significantly, silence of Nrf2 expression abolishes cytoprotection of 10 and 11, indicating targeting Nrf2 activation is pivotal for their cellular functions. Taken together, the two lead compounds discovered here with potent neuroprotective functions against oxidative stress via Nrf2 activation merit further development as therapeutic or chemopreventive candidates for neurodegenerative disorders.

Palladium-Catalyzed Asymmetric Intramolecular Reductive Heck Desymmetrization of Cyclopentenes: Access to Chiral Bicyclo[3.2.1]octanes

Yuan, Zhenbo,Feng, Ziwen,Zeng, Yuye,Zhao, Xiaobin,Lin, Aijun,Yao, Hequan

supporting information, p. 2884 - 2888 (2019/02/16)

A palladium-catalyzed asymmetric reductive Heck reaction of unactivated aliphatic alkenes, with eliminable β-hydrogen atoms, has been realized for the first time. A series of optically active bicyclo[3.2.1]octanes bearing chiral quaternary and tertiary carbon stereocenters were obtained in good yields with excellent enantioselectivities, exhibiting good functional-group tolerance and scalability. Moreover, deuterated optically active bicyclo[3.2.1]octanes were also obtained in high efficiency.

Formation of substituted 1-naphthols and related products via dimerization of alkyl 3-(o-halo(het)aryl)-oxopropanoates based on a CuI-catalyzed domino C-arylation/condensation/aromatization process

Weischedel, Heike,Sudheendran, Kavitha,Mikhael, Alevtina,Conrad, Jürgen,Frey, Wolfgang,Beifuss, Uwe

, p. 3454 - 3467 (2016/06/06)

Substrates bearing both a β-ketoester moiety and a (het)aryl halide structure element were dimerized to 1-naphthols and related products in the presence of catalytic amounts of CuI in isopropanol. The reaction starts with an intermolecular C-arylation, which is followed by an intramolecular condensation. The final aromatization delivers the highly substituted products with yields up to 81%.

, p. 13237 - 13252 (2007/10/03)

Simple and high yielding syntheses of several β-keto esters, catalysed by zeolite Hβ are reported. The methods developed include condensation of aldehydes with ethyl diazoacetate and transesterification of β-keto esters with primary, secondary, allylic and benzylic alcohols etc., all catalysed by Hβ. It was further observed that under microwave irradiation the yields of many aromatic β-keto esters were enhanced appreciably.

SYNTHESIS OF ETHYL ortho-SUBSTITUTED BENZOYLACETATES AND INVESTIGATION OF THE INFLUENCE OF ortho-SUBSTITUENTS ON KETO-ENOL TAUTOMERISM AND MS FRAGMENTATION BEHAVIOUR

Sicker, Dieter,Mann, Gerhard

, p. 839 - 850 (2007/10/02)

A series of seven ethyl 2-acetyl-(2-substituted benzoyl)acetates II-VIII was synthesized, together with their parent compound I, from the corresponding acid chlorides.The tautomerism of these β-tricarbonyl compounds in tetrachloromethane was studied by 1H NMR spectroscopy and former results concerning this problem were critically evaluated.A further series of seven ortho-substituted ethyl benzoylacetates X-XV and XVII was obtained from the corresponding precursors II-VIII.The keto-enol tautomerism of these β-keto esters was studied by 1H NMR in different solventsand compared with ethyl benzoylacetate IX as standard.Differences caused by the ortho-substituents are discussed.Investigation of the mass spectrometric fragmentation of the β-keto esters IX-XV and XVII showed both common fragmentation pathways due to the same substance class and typical differences in relative intensities according to the nature of the ortho-substituent.
