39880-81-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 39880-81-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,8,8 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 39880-81:
(7*3)+(6*9)+(5*8)+(4*8)+(3*0)+(2*8)+(1*1)=164
164 % 10 = 4
So 39880-81-4 is a valid CAS Registry Number.

Tetraethylammonium iodide catalyzed synthesis of diaryl ketones via the merger of cleavage of C-C double bonds and recombination of aromatic groups

Zeng, Xianghua,Xu, Daqian,Miao, Chengxia,Xia, Chungu,Sun, Wei

, p. 46494 - 46497 (2014/12/10)

An efficient method for synthesizing diaryl ketones via merging of oxidative cleavage of C-C double bonds and recombination of aromatic groups is developed with Et4NI (2.5 mol%) as the catalyst and NaIO4 as the oxidant. The control experiments provide valuable mechanistic insights into the formation of diaryl ketones, and suggest that NaIO4 serves as an epoxidation and nucleophilic deformylation reagent.

Platelet antiaggregant methoxyphenylthienyl ketoxime ethers: Synthesis and structure-activity relationships

Varache-Lembege,Nuhrich,Renard,Duboudin,Vercauteren,Devaux

, p. 417 - 424 (2007/10/02)

Some new oximinoalkanoic (n = 2,3,4) esters and acids derived from methoxyphenylthienyl ketones have been synthesized and evaluated in vitro for their inhibitory effects on arachidonic acid-induced human platelet aggregation. Of the eighteen oximinoethers
