Check Digit Verification of cas no

The CAS Registry Mumber 15796-89-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,7,9 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 15796-89:
(7*1)+(6*5)+(5*7)+(4*9)+(3*6)+(2*8)+(1*9)=151
151 % 10 = 1
So 15796-89-1 is a valid CAS Registry Number.

Visible-Light-Driven Intermolecular [2+2] Cycloadditions between Coumarin-3-Carboxylates and Acrylamide Analogs

Liu, Qiang,Zhu, Fu-Ping,Jin, Xiao-Ling,Wang, Xiao-Ju,Chen, Han,Wu, Li-Zhu

, p. 10326 - 10329 (2015)

This paper reports a room temperature visible-light-driven protocol for the intermolecular [2+2] cycloadditions between coumarin-3-carboxylates and acrylamides analogs by an energy-transfer process. Using an iridium complex FIrPic as a photosensitizer and a 3W blue LED as a light source, an array of cyclobutabenzocypyranones were prepared in moderate to excellent yields.

Palladium-catalyzed picolinamide-directed coupling of C(sp2)-H and C(sp2)-H: A straightforward approach to quinolinone and pyridone scaffolds

Zhang, Dengyou,Gao, Feng,Nian, Yong,Zhou, Yu,Jiang, Hualiang,Liu, Hong

, p. 7509 - 7511 (2015)

An unprecedented palladium-catalyzed picolinamide-directed coupling of C(sp2)-H and C(sp2)-H has been developed with exclusive formation of the six-membered ring heterocyclics-quinolinone and pyridone. The method employs cyclic hypervalent iodine as oxidant and features good functional-group tolerance. Another advantage of this reaction is that sequential C-H/C-H and C-H/N-H coupling could be achieved. This journal is

Excited-State Copper Catalysis for the Synthesis of Heterocycles

Heterocycles are one of the largest groups of organic moieties with significant medicinal, chemical, and industrial applications. Herein, we report the discovery and development of visible-light-induced, synergistic excited-state copper catalysis using a combination of Cu(IPr)I as a catalyst and rac-BINAP as a ligand, which produces more than 10 distinct classes of heterocycles. The reaction tolerates a broad array of functional groups and complex molecular scaffolds, including derivatives of peptides, natural products, and marketed drugs. Preliminary mechanistic investigation suggests in situ generations of [Cu(BINAP)2]+ and [Cu(IPr)2]+ catalysts that work cooperatively under visible-light irradiation to facilitate catalytic carbo-aroylation of unactivated alkenes, affording a wide range of useful heterocycles.

Photoinduced Hydroarylation and Cyclization of Alkenes with Luminescent Platinum(II) Complexes

Cheng, Hanchao,Lam, Tsz-Lung,Liu, Yungen,Tang, Zhou,Che, Chi-Ming

, p. 1383 - 1389 (2020/11/30)

Photoinduced hydroarylation of alkenes is an appealing synthetic strategy for arene functionalization. Herein, we demonstrated that aryl radicals generated from electron-deficient aryl chlorides/bromides could be trapped by an array of terminal/internal aryl alkenes in the presence of [Pt(O^N^C^N)] under visible-light (410 nm) irradiation, affording anti-Markovnikov hydroarylated compounds in up to 95 % yield. Besides, a protocol for [Pt(O^N^C^N)]-catalyzed intramolecular photocyclization of acrylanilides to give structurally diverse 3,4-dihydroquinolinones has been developed.
