659737-56-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 659737-56-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,9,7,3 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 659737-56:
(8*6)+(7*5)+(6*9)+(5*7)+(4*3)+(3*7)+(2*5)+(1*6)=221
221 % 10 = 1
So 659737-56-1 is a valid CAS Registry Number.

Novel one-pot synthesis of xanthones via sequential fluoride ion-promoted fries-type rearrangement and nucleophilic aromatic substitution

Fujimoto, Yuuki,Itakura, Ryohei,Hoshi, Hiroki,Yanai, Hikaru,Ando, Yoshio,Suzuki, Keisuke,Matsumoto, Takashi

supporting information, p. 2575 - 2580 (2013/12/04)

A novel and efficient synthesis of xanthones is described. 2-(Trimethylsilyl)phenyl 2-fluorobenzoate derivatives undergo Fries-type rearrangement and intramolecular SNAr reaction in a one-pot sequential manner under fluoride ion-promoted mild conditions. The method provides efficient access to xanthones that have significant steric congestion around the C9 carbonyl, which are not readily available by conventional methods.

Anti-selective catalytic asymmetric nitroaldol reaction via a heterobimetallic heterogeneous catalyst

Nitabaru, Tatsuya,Nojiri, Akihiro,Kobayashi, Makoto,Kumagai, Naoya,Shibasaki, Masakatsu

supporting information; experimental part, p. 13860 - 13869 (2010/01/06)

Full details of an anti-selective catalytic asymmetric nitroaldol reaction promoted by a heterobimetallic catalyst comprised of Nd5O(O iPr)13, an amide-based ligand, and NaHMDS (sodium hexamethyldisilazide) are described.

Antibacterial alkoxybenzamide inhibitors of the essential bacterial cell division protein FtsZ

Ring-substituted 1,2-dialkylated 1,2-bis(hydroxyphenyl)ethanes. 2. Synthesis and estrogen receptor binding affinity of 4,4'-, 5,5'-, and 6,6'-disubstituted metahexestrols

Hartmann,Heindl,Schonenberger

, p. 577 - 585 (2007/10/02)

The synthesis of symmetrically 4,4'-, 5,5'-, and 6,6'-disubstituted derivatives of the mammary tumor inhibiting antiestrogen metahexestrol [meso-3,4-bis(3-hydroxyphenyl)hexane] (1) are described [4,4'-disubstituents: F(2), Cl (3), Br (4), I (5), CH2N(CH3)2 (6), CH3 (7), CH2OCH3 (8), CH2OC2H5 (9), CH2OH (10), NO2 (11), NH2 (12), N(CH3)2 (13), COCH3 (14), and C2H5 (15); 5,5'-substituents: OH (16) and Cl (17); 6,6'-disubstituents: OH (18), F (19), Cl (20), and CH3 (21)]. The synthesis of 1-3, 16, and 19 was accomplished by reductive coupling of the propiophenones with TiCl4/Zn and subsequent hydrogenation of the cis-3,4-diphenylhex-3-enes. Compounds 17, 18, 20, and 21 were synthesized by coupling the 1-phenyl-1-propanols with TiCl3/LiAlH4 and separation of the meso diastereomers, while 4-15 were obtained by substitution of metahexestrol. The binding affinity of these compounds to the calf uterine estrogen receptor was measured relative to that of [3H]estradiol by a competitive binding assay. The test compounds showed relative binding affinity (RBA) values between 15 and 0.5% were evaluated in the mouse uterine weight test. They showed a similar (2 and 12), slightly increased (19 and 21), or strongly enhanced (7 and 20) estrogenicity compared to that of metahexestrol. Compounds 1, 2, 7, 12, and 21 exhibited antiestrogenic activity inhibiting the estrone-stimulated uterine growth (24 to 60% inhibition).
