65555-88-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 65555-88-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,5,5 and 5 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 65555-88:
(7*6)+(6*5)+(5*5)+(4*5)+(3*5)+(2*8)+(1*8)=156
156 % 10 = 6
So 65555-88-6 is a valid CAS Registry Number.

Chiral azo compounds: Enantioselective synthesis and transformations into β-amino alcohols and α-amino acids with a quaternary stereocenter

Dietz, Friedrich R.,Prechter, Agnes,Gr?ger, Harald,Heinrich, Markus R.

, p. 655 - 657 (2011/03/21)

Taking advantage of radical carboaminations producing azo compounds, a new chemo-enzymatic approach to enantiomerically enriched azo alcohols, β-amino alcohols and non-natural (aromatic) amino acids with a quaternary stereocenter is reported.

Synthesis of Optically Pure α-Alkylated α-Amino Acids and a Single-Step Method for Enatiomeric Excess Determination

Kruizinga, Wim H.,Bolster, John,Kellogg, Richard M.,Kamphuis, Johan,Boesten, Wilhelmus H. J.,et al.

, p. 1826 - 1827 (2007/10/02)

A method for the enzymatic resolution of the amides of some racemic α-alkylated amino acids is described as well as a method involving derivatization with (S)-2-chloropropionyl chloride followed by 1H NMR analysis to establish the enantiomeric excesses of the free amino acids.
