10268-70-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 10268-70-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,2,6 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 10268-70:
(7*1)+(6*0)+(5*2)+(4*6)+(3*8)+(2*7)+(1*0)=79
79 % 10 = 9
So 10268-70-9 is a valid CAS Registry Number.

Regiospecific phenyl esterification to some organic acids catalyzed by combined Lewis acids

Roy,Mamun, A. H. Al

, p. 2975 - 2981 (2006)

A new and efficient method for the preparation of various phenyl esters has been achieved by a simple reaction of an acid with phenol in the presence of anhyd. ZnCl2 and a catalytic amount of AlCl3. This combined Lewis acid also catalyzes the selective phenyl esterification to different dioic acids and is very simple and high yielding. Copyright Taylor & Francis Group, LLC.

Chain-growth polycondensation for well-defined aramide. Synthesis of unprecedented block copolymer containing aramide with low polydispersity

Yokozawa, Tsutomu,Ogawa, Miyuki,Sekino, Atsushi,Sugi, Ryuji,Yokoyama, Akihiro

, p. 15158 - 15159 (2007/10/03)

Poly(p-benzamide) with a defined molecular weight and a low polydispersity and a block copolymer containing this well-defined aramide was synthesized. Phenyl 4-aminobenzoate, which would yield poly(p-benzamide), did not polymerize under the conditions of

Substituent effects on the base-catalysed hydrolysis of phenyl esters of para-substituted benzoic acids

Bauerova, Ingrid,Ludwig, Miroslav

, p. 1777 - 1790 (2007/10/03)

Seventeen model phenyl esters of 4-substituted benzoic acids were synthesised by the reaction of substituted benzoyl chlorides with phenol in aqueous alkaline solutions (Schotten-Baumann reaction), in pyridine (Einhorn reaction), or by the reaction of substituted benzoic acids with phosphorus oxychloride. Structures and purity of the model compounds were confirmed by 1H NMR and 13C NMR spectroscopy as well as by HPLC and elemental analysis. Phenyl 4-aminobenzoate was synthesised by reduction of phenyl 4-nitrobenzoate in methanol on palladium. Kinetics of base-catalysed hydrolysis of model phenyl esters occurring by the BAc2 mechanism were measured by UV spectrophotometry in 50% (v/v) aqueous dimethyl sulfoxide solutions at 25°C under pseudo-first-order conditions, (c[NaOH] = 0.001-1.0 mol l-1). The addition of OH- to phenyl benzoates was used to establish the kinetic J-E acidity scale. Linear relation between J-E and log kobs with the slope near unity was found for all the model compounds. The kinetic constants of hydrolysis of phenyl esters of 4-substituted benzoic acids precisely obey the Hammett relationship (σp) with ρ = 2.44. Quantitatively comparable results have been obtained by application of Alter-native Interpretation of Substituent Effects theory (AISE) using the σi set of substituent constants.
