200731-02-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 200731-02-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,7,3 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 200731-02:
(8*2)+(7*0)+(6*0)+(5*7)+(4*3)+(3*1)+(2*0)+(1*2)=68
68 % 10 = 8
So 200731-02-8 is a valid CAS Registry Number.

The synthesis of L-(+)-homophenylalanine hydrochloride

Xu, Qianyong,Wang, Guoxin,Wang, Xuechao,Wu, Tongxing,Pan, Xinfu,Chan, Albert S.C.,Yang, Teng-Kuei

, p. 2309 - 2314 (2000)

L-(+)-Homophenylalanine hydrochloride was synthesized from N-phthaloyl-L-(-)-asparitc anhydride 2 in three steps in 55% overall yield with 99% ee. Copyright (C) 2000 Elsevier Science Ltd.

Regio- and stereoselective 1,6-photocyclization of aspartic acid- derived chiral γ-ketoamides[1]

Griesbeck, Axel G.,Heckroth, Heike,Schmickler, Hans

, p. 3137 - 3140 (2007/10/03)

Chiral α-acylamino γ-ketoamides 2 were irradiated and regioisomeric 1,6-cyclization products 3 and 4 obtained in high yields. Symmetrically N,N- disubstituted substrates 2a,b reacted diastereoselectively to give the all- cis products 3a,b in high yields. High 1,3-asymmetric induction was also observed for the unsymmetrically N,N-disubstituted 2d and 2e. The stereoselectivity of these reactions is discussed in terms of SOC-controlled spin inversion geometries.

A Simple Approach to β-Amino Acids by Acylation of Arenes with N-Acyl Aspartic Anhydrides

Griesbeck, Axel G.,Heckroth, Heike

, p. 1243 - 1244 (2007/10/03)

Friedel-Crafts acylation of arenes (benzene, toluene, o-xylene) with N-protected (Bz, Ac, Ac-Bn, Ts, Tfac, N,N-Pht) aspartic anhydrides (1a-1f) resulted in mixtures of α- and β-amino acids. The β/ α-selectivity could be optimized for alkylated arenes (toluene, xylene) and the N-Ac, N-Bn protected 1c.
