142758-96-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 142758-96-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,7,5 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 142758-96:
(8*1)+(7*4)+(6*2)+(5*7)+(4*5)+(3*8)+(2*9)+(1*6)=151
151 % 10 = 1
So 142758-96-1 is a valid CAS Registry Number.

Synthesis of chiral oxazolidin-2-ones by 1,2-amino alcohols, carbon dioxide and electrogenerated acetonitrile anion

Feroci, Marta,Gennaro, Armando,Inesi, Achille,Orsini, Monica,Palombi, Laura

, p. 5863 - 5865 (2002)

An improved electrochemical synthesis of chiral oxazolidin-2-ones from chiral 1,2-amino alcohols is obtained by direct electrolysis of solutions of MeCN-TEAP containing the amino alcohol, with subsequent CO2 bubbling and addition of TsCl. This

Practical Preparation of Chiral 4-Substituted 2-Oxazolidinones

Ishizuka, Tadao,Kimura, Koreichi,Ishibuchi, Seigo,Kunieda, Takehisa

, p. 991 - 994 (2007/10/02)

A versatile and practical route to both enantiomers of a wide variety of 4-substituted 2-oxazolidinones from the parent heterocycle is provided by regioselective substitutions via 4-methoxy derivative followed by chromatographic separation of the diastereomers derived from N-2-exo-methoxy-1-apocamphanecarbonylation.
