739-45-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 739-45-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,3 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 739-45:
(5*7)+(4*3)+(3*9)+(2*4)+(1*5)=87
87 % 10 = 7
So 739-45-7 is a valid CAS Registry Number.

Equilibrium acidities of some sulfones and sulfoxides in tetrahydrofuran

Streitwieser, Andrew,Wang, George Peng,Bors, Daniel A.

, p. 10103 - 10112 (2007/10/03)

Ion pair acidities are reported in tetrahydrofuran (THF) solution for the lithium and cesium salts of several sulfones and one sulfoxide. These salts are shown to be monomeric in the THF solutions studied. Thermodynamic constants are reported for several salts. The results and some conductivity studies show that both the lithium and cesium salts are contact ion pairs in THF. Because of ion association the relative pKs are slightly lower for cesium salts and much lower for lithium salts than for the free ions in DMSO solution.

Carbon Acidity. 79. Acidity of Enolate Equivalent Compounds: Oxime Ethers

Ciula, James C.,Streitwieser, Andrew

, p. 1989 - 1993 (2007/10/02)

A series of benzylic oxime ethers were synthesized (CH3ON=C(CH2Ar)2, Ar = phenyl (1), 4-biphenylyl (2), 1-naphthyl (3), and the equilibrium ion pair acidities in THF were determined.The lithium ion pair acidity of 1 was found to be approximately 5 pK units lower than the corresponding cesium ion pair acidity.The oxime ethers are approximately 10 orders of magnitude less acidic than their corresponding ketones for cesium ion pairs.Thermodynamic parameters for the equilibrium acidities were measured and are consistent for contact ion pair monomers being the important species in solution.An aggregation study also indicated that these cesium oxime ether enolates exist mainly as ion pair monomers.The role of gegenion in the stability of oxime ether anions is discussed.
