188973-49-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 188973-49-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,9,7 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 188973-49:
(8*1)+(7*8)+(6*8)+(5*9)+(4*7)+(3*3)+(2*4)+(1*9)=211
211 % 10 = 1
So 188973-49-1 is a valid CAS Registry Number.

Electrophotochemical Ring-Opening Bromination oftert-Cycloalkanols

Yamamoto, Kosuke,Toguchi, Hiroyuki,Kuriyama, Masami,Watanabe, Shin,Iwasaki, Fumiaki,Onomura, Osamu

, p. 16177 - 16186 (2021/09/13)

An electrophotochemical ring-opening bromination of unstrainedtert-cycloalkanols has been developed. This electrophotochemical method enables the oxidative transformation of cycloalkanols with 5- to 7-membered rings into synthetically useful ω-bromoketones without the use of chemical oxidants or transition-metal catalysts. Alkoxy radical species would be key intermediates in the present transformation, which generate through homolysis of the O-Br bond in hypobromite intermediates under visible light irradiation.

Palladium-Catalyzed Room-Temperature Acylative Suzuki Coupling of High-Order Aryl Borons with Carboxylic Acids

Si, Shufen,Wang, Chen,Zhang, Nan,Zou, Gang

, p. 4364 - 4370 (2016/06/09)

This note describes a dimethyl dicarbonate-assisted, Pd(OAc)2/PPh3-catalyzed acylative Suzuki coupling of carboxylic acids with diarylborinic acids or tetraarylboronates for practical and efficient synthesis of sterically undemanding aryl ketones at room temperature. More than just cost-effective alternatives to aryl boronic acids, diarylborinic acids and tetraarylboronates displayed higher reactivity in the acylative Suzuki coupling. A variety of alkyl aryl ketones, including those bearing a hydroxy, bromo, or carbonyl group, could be readily obtained in modest to excellent yields.

Synthesis of neuroprotective cyclopentenone prostaglandin analogs: Suppression of manganese-induced apoptosis of PC12 cells

Furuta, Kyoji,Maeda, Masahide,Hirata, Yoko,Shibata, Shoko,Kiuchi, Kazutoshi,Suzuki, Masaaki

, p. 5487 - 5491 (2008/03/13)

The synthesis and evaluation for anti- and proapoptotic properties of cyclopentenone prostaglandin analogs are described. Novel J-type analogs of NEPP11 with a cross-conjugated cyclopentadienone moiety and a lipophilic ω-side chain suppressed manganese io
