373380-62-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 373380-62-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,3,3,8 and 0 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 373380-62:
(8*3)+(7*7)+(6*3)+(5*3)+(4*8)+(3*0)+(2*6)+(1*2)=152
152 % 10 = 2
So 373380-62-2 is a valid CAS Registry Number.

A study of enantioselective syntheses by Sharpless asymmetric oxidation for aryl sulfoxides containing oxygen groups at the ortho position

Takei, Takanori,Takayama, Jun,Xuan, Meiyan,Tomoda, Misa,Miyamae, Hiroshi,Sakamoto, Takeshi

Abstract: While ortho-alkoxy aryl sulfoxides including various substituents were synthesized by Sharpless asymmetric oxidation reaction, we optimized the reaction conditions and screened better combination of starting materials to obtain high enantioselectivity. The result suggested new information that electron-withdrawing substituents on the aromatic ring have a strong influence upon enantioselectivity of the products. Also, several chiral ligands for Sharpless asymmetric oxidation reaction were evaluated to improve the enantioselectivity. Graphic abstract: High enantioselectivity of ortho-alkoxy aryl chiral sulfoxides have been achieved by Sharpless oxidation reaction using Ti(O-i-Pr)4 and diethyl tartrate under anhydrous condition. In particular, the enantioselctivity of products was influenced by electron-withdrawing substituents on the aromatic ring, such as nitro, ester and aldehyde groups.[Figure not available: see fulltext.]

Synthesis and investigation of conformationally restricted analogues of lavendustin A as cytotoxic inhibitors of tubulin polymerization

Mu, Fanrong,Lee, Debbie J.,Pryor, Donald E.,Hamel, Ernest,Cushman, Mark

, p. 4774 - 4785 (2007/10/03)

A series of conformationally restricted analogues were synthesized in order to elucidate the possible effects of different amide conformations of lavendustin A derivatives on cytotoxicity in cancer cell cultures and on inhibition of tubulin polymerization. The conformationally restricted analogues were based on the oxazinedione and isoindolone ring systems. In addition, the amide bond was replaced by both cis and trans alkene moieties. Surprisingly, the results indicated very little effect of conformational restriction on biological activity. Because all of the compounds synthesized had similar cytotoxicities and potencies as tubulin polymerization inhibitors, the side chain present on the aniline ring system does not appear to be important in the biological effects of the lavendustins. The hydroquinone ring of lavendustin A may be a more important determinant of the biological activity than the structure surrounding the aniline ring.

p-aminophenol derivative compounds and dye compositions containing same

, (2008/06/13)

The p-aminophenol derivative compounds of formula (1), or their physiologically compatible water-soluble salts: 1are useful as developer compounds in oxidation dye compositions for keratin fibers. Oxidation dye compositions for keratin fibers, including hair, and methods of dyeing hair using the p-aminophenol derivative compounds are also described.
