13709-07-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13709-07-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,0 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 13709-07:
(7*1)+(6*3)+(5*7)+(4*0)+(3*9)+(2*0)+(1*7)=94
94 % 10 = 4
So 13709-07-4 is a valid CAS Registry Number.

Design, synthesis, and evaluation of a water soluble C5-monoketone type curcumin analogue as a potent amyloid β aggregation inhibitor

Hotsumi, Mayumi,Tajiri, Misato,Nikaido, Yuri,Sato, Taki,Makabe, Koki,Konno, Hiroyuki

supporting information, p. 2157 - 2161 (2019/07/03)

A structure activity relationship study of curcumin analogues for the inhibition of amyloid β aggregation is described. Optimization of the o-phenol and olefin spacer resulted in the identification of the C5-monoketone type curcumin analogue AY1319, which

Paragraph 0698; 0699; 0700, (2015/07/02)

A polymerizable compound has a practical low melting point, excellent solubility in a general-purpose solvent, and can produce an optical film at low cost, exhibits low reflected luminance, and achieves uniform conversion of polarized light over a wide wavelength band, an optically anisotropic article. A carbonyl compound is useful as a raw material for producing the polymerizable compound. (In the formula (I), Y1 to Y8 represent —C(═O)—O—, G1 and G2 represent a C1-20 divalent linear aliphatic group, Z1 and Z2 represent a C2-10 alkenyl group that is unsubstituted, or substituted with a halogen atom, Ax represents a C2-30 organic group with at least one aromatic ring, Ay represents a hydrogen atom or C1-20 alkyl group, A1 represents a trivalent aromatic group, A2 and A3 represent a C3-30 divalent alicyclic hydrocarbon group, A4 and A5 represent a C6-30 divalent aromatic group or the like, and Q1 represents a hydrogen atom.)

Concise syntheses and biological activities of ganomycin I and fornicin A

Yajima, Arata,Urao, Shota,Katsuta, Ryo,Nukada, Tomoo

, p. 731 - 738 (2014/03/21)

The first enantioselective syntheses of ganomycin I, a meroterpenoid isolated from the Vietnamese mushroom Ganoderma colossum, and the related meroterpenoid fornicin A were accomplished. Our methodology for the total syntheses of these compounds featured the construction of the butenolide moiety by asymmetric dihydroxylation followed by Julia-Kocienski type olefin formation and ring-closing metathesis reactions. The absolute configurations of the two natural products were determined by comparisons of specific rotation. A cell-based assay of the synthetic compounds with transfected human embryonic kidney 293 tetoff (E-PR293) cells indicated that ganomycin I possesses cytotoxicity and fornicin A possesses weak anti-HIV-1 protease activity without cytotoxicity.
