144453-64-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 144453-64-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,4,5 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 144453-64:
(8*1)+(7*4)+(6*4)+(5*4)+(4*5)+(3*3)+(2*6)+(1*4)=125
125 % 10 = 5
So 144453-64-5 is a valid CAS Registry Number.

Syntheses of Polycyclic Tetrahydrofurans by Cascade Reactions Consisting of Five-Membered Ring Selective Prins Cyclization and Friedel-Crafts Cyclization

Sakata, Yuki,Yasui, Eiko,Takatori, Kazuhiko,Suzuki, Yuji,Mizukami, Megumi,Nagumo, Shinji

, p. 9103 - 9118 (2018)

A novel cascade reaction consisting of a five-membered ring selective Prins cyclization and a subsequent Friedel-Crafts cyclization is reported. Treatment of homocinnamyl alcohols and aromatic aldehydes with BF3·OEt2 in CH2/sub

Photoredox-Coupled F-Nucleophilic Addition: Allylation of gem-Difluoroalkenes

Liu, Haidong,Ge, Liang,Wang, Ding-Xing,Chen, Nan,Feng, Chao

supporting information, p. 3918 - 3922 (2019/02/19)

A novel strategy for the expedient construction of CF3-embeded tertiary/quarternary carbon centers was developed by taking advantage of photoredox catalysis. Thanks to a key step of single-electron oxidation, electron-rich gem-difluoroalkenes, which otherwise are essentially reluctant towards F-nucleoplilic addition, now readily participate in this fluoroallylation reaction. Furthermore, this strategy provides an elegant example for the generation, as well as functionalization, of α-CF3-substituted benzylic radical intermediates using cheap and readily available starting materials.

Identification of a 4-(hydroxymethyl)diarylhydantoin as a selective androgen receptor modulator

Nique, Francois,Hebbe, Severine,Triballeau, Nicolas,Peixoto, Christophe,Lefrancois, Jean-Michel,Jary, Helene,Alvey, Luke,Manioc, Murielle,Housseman, Christopher,Klaassen, Hugo,Van Beeck, Kris,Guedin, Denis,Namour, Florence,Minet, Dominque,Van Der Aar, Ellen,Feyen, Jean,Fletcher, Stephen,Blanque, Roland,Robin-Jagerschmidt, Catherine,Deprez, Pierre

supporting information, p. 8236 - 8247,12 (2020/09/15)

Structural modification performed on a 4-methyl-4-(4-hydroxyphenyl) hydantoin series is described which resulted in the development of a new series of 4-(hydroxymethyl)diarylhydantoin analogues as potent, partial agonists of the human androgen receptor. T
