14253-59-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 14253-59-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,2,5 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 14253-59:
(7*1)+(6*4)+(5*2)+(4*5)+(3*3)+(2*5)+(1*9)=89
89 % 10 = 9
So 14253-59-9 is a valid CAS Registry Number.

Cinchona alkaloid derivative modified Fe3O4nanoparticles for enantioselective ring opening of: Meso -cyclic anhydrides

Soni, Hemant P.,Tomer, Sanjiv O.

, p. 2495 - 2507 (2022/02/11)

In the present work, the molecular framework of quinidine was modified at the methoxy functional group of the C6′ carbon of the quinoline moiety with a long-chain carboxylic acid group (-COOH) and it was used as a capping agent during the synthesis of Fe3

Highly Effective and Practical Enantioselective Synthesis of Half-Esters of Bicycloheptanedicarboxylic Acid

Ohtani, Mitsuaki,Matsuura, Takaharu,Watanabe, Fumihiko,Narisada, Masayuki

, p. 4120 - 4123 (2007/10/02)

An effective and practical enantioselective synthesis of half-esters of bicycloheptane-2,3-dicarboxylic acid was developed by enantioselective fission of ?-symmetrical cyclic anhydrides with chiral mandelic acid derivatives, followed by deprotectio

Optical and Neutron Inelastic Scattering Study of 2,3-Dimethylnorbornanes

Brunel, Yvon,Coulombeau, Christian,Coulombeau, Christiane,Jobic, Herve

, p. 2008 - 2015 (2007/10/02)

We have measured the infrared, Raman, and neutron vibrational spectra of the 2,3-dimethylnorbornanes with two CH3 or CD3 groups in the 2- and 3-exo or endo positions.A normal-coordinate analysis has been carried out.No coupling reflecting the strain due to the methyl group appears in the C-CH3 bending and torsional modes of the trans isomer, but appears in the cis-exo isomer (average value 23 cm-1) and in the cis-endo isomer (average value 28 cm-1.The frequencies are used for the determination of the thermodynamic contribution to the standard free energy differences.
