5997-56-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5997-56-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,9 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5997-56:
(6*5)+(5*9)+(4*9)+(3*7)+(2*5)+(1*6)=148
148 % 10 = 8
So 5997-56-8 is a valid CAS Registry Number.

Regio- and chemoselective rearrangement of terminal epoxides into methyl alkyl and aryl ketones

Tian, Yingying,Jürgens, Eva,Kunz, Doris

, p. 11340 - 11343 (2018/10/31)

The development of the highly active pincer-type rhodium catalyst 2 for the nucleophilic Meinwald rearrangement of functionalised terminal epoxides into methyl ketones under mild conditions is presented. An excellent regio- and chemoselectivity is obtained for the first time for aryl oxiranes.

NIS-mediated ring-closure/opening cascade reactions of allylamides: An expedient route to oxazolines

Hu, Yancheng,Li, Xincheng,Wan, Boshun

, p. 6935 - 6943 (2015/08/24)

An unprecedented NIS-mediated ring-closure/opening cascade reaction of allylamides is developed. The substrates with various functionalities were well tolerated and the scope can be extended to allylic carboxylates. Notably, the resulting iodinated chain

Copper-catalyzed trifluoromethylation and cyclization of aromatic-sulfonyl-group-tethered alkenes for the construction of 1,2-benzothiazinane dioxide type compounds

Dong, Xiang,Sang, Rui,Wang, Qiang,Tang, Xiang-Ying,Shi, Min

, p. 16910 - 16915 (2014/01/06)

A multi-talented system: An efficient copper-catalyzed tandem trifluoromethylation/annulation of an electron-deficient aromatic ring has been developed. This method provides a powerful and straightforward way to synthesize trifluoromethylated 1,2-benzothiazinane dioxides under mild conditions (see scheme). The mechanism was investigated by a series of kinetic experiments and isotopic labeling studies.
