Check Digit Verification of cas no

The CAS Registry Mumber 134420-70-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,4,2 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 134420-70:
(8*1)+(7*3)+(6*4)+(5*4)+(4*2)+(3*0)+(2*7)+(1*0)=95
95 % 10 = 5
So 134420-70-5 is a valid CAS Registry Number.

Improved enzymatic syntheses of valuable β-arylalkyl-β-amino acid enantiomers

Tasnadi, Gabor,Forro, Enik,Fueloep, Ferenc

experimental part, p. 793 - 799 (2010/06/20)

The enantioselective (E~ 200) Burkholderia cepacia-catalysed hydrolyses of β-amino esters with H2O (0.5 equiv.) in t-BuOMe or in i-Pr2O at 45 °C are described. The enantiomers of biologically relevant β-arylalkyl-substituted β-amino acids, and especially (R)-3-amino-3-(2,4,5-trifluorophenyl)butanoic acid, the intermediate of the new antidiabetic drug sitagliptine, were prepared with high enantiomeric excesses (ee≥96%) and in good yields (≥42%).

Copper-catalyzed amine-alkyne-alkyne addition reaction: An efficient method for the synthesis of γ,δ-alkynyl-β-amino acid derivatives

Zhou, Lei,Shuai, Qi,Jiang, Huan-Feng,Li, Chao-Jun

scheme or table, p. 11668 - 11674 (2010/04/28)

A simple and efficient method for the synthesis of γ,δ-alkynyl- β-amino acid derivatives by a copper-catalyzed three-component amine-alkyne-alkyne addition reaction was developed. Various γ,δ-alkynyl-βamino acid derivatives were synthesized in moderate to

Efficient synthesis of γ,δ-alkynyl-β-amino acid derivatives by a new copper-catalyzed amine-alkyne-alkyne addition reaction

Zhou, Lei,Jiang, Huan-Feng,Li, Chao-Jun

experimental part, p. 2226 - 2230 (2009/10/02)

A simple and efficient method for the synthesis of γ,δ-alkynyl- β-amino acid derivatives by a new copper-catalyzed amines-alkynes-alkynes addition was developed. Various γ,δ-alkynyl-β-amino acid derivatives were obtained in moderate to good yields in one step.

Synthesis of substituted piperidines, decahydroquinolines and octahydroindolizines by radical rearrangement reactions of 2-alkylideneaziridines

Prévost, Natacha,Shipman, Michael

, p. 7165 - 7175 (2007/10/03)

Rearrangement of a variety of 3-(2-methyleneaziridin-1-yl)propyl radicals, generated using Bu3SnH/AIBN by homolytic cleavage of phenylselenide substituted 2-methyleneaziridines, produces 3-methylenepiperidines in yields ranging from 58 to 68%.
