614-44-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 614-44-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,1 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 614-44:
(5*6)+(4*1)+(3*4)+(2*4)+(1*4)=58
58 % 10 = 8
So 614-44-8 is a valid CAS Registry Number.

Domino Two-Step Oxidation of β-Alkoxy Alcohols to Hemiacetal Esters: Linking a Stoichiometric Step to an Organocatalytic Step with a Common Organic Oxidant

Targel, Tom,Ramesh, Palakuri,Portnoy, Moshe

supporting information, p. 3017 - 3021 (2018/06/27)

Primary and secondary β-alkoxy alcohols can be cleanly and efficiently oxidized into hemiacetal esters in a cascade two-step process. mCPBA serves both as a stoichiometric oxidant in the first TEMPO-catalyzed step, converting alcohols to aldehydes/ketones, and as a reagent in the second Baeyer–Villiger stoichiometric oxidation, transforming the aldehydes/ketones into hemiacetal esters. The use of an oxidant common to both steps enables the domino reaction to proceed under a single experimental setting. Longer oxidative cascade sequences are possible when this new methodology is applied to suitable substrates.

The Effect of pH Control on the Selective Ruthenium-Catalyzed Oxidation of Ethers and Alcohols with Sodium Hypochlorite

Gonsalvi, Luca,Arends, Isabel W. C. E.,Moilanen, Pasi,Sheldon, Roger A.

, p. 1321 - 1328 (2007/10/03)

Highly selective oxidations of ethers to esters or lactones and of secondary alcohols to ketones were achieved using catalytic amounts of various Ru precursors and the theoretical amount of NaOCl. Reactions were carried out in biphasic solvent mixtures at constant pH 9-9.5 via either feed-on-demand addition of HCl and NaOH or in the presence of NaHCO3/Na 2CO3 buffer. The catalyst could be easily recycled for at least 4 times with only minor loss in selectivity. Products were generally recovered by simple phase separation and evaporation of the organic solvent. The effects of catalyst precursor, additives and pH control method are also described.
