80656-34-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 80656-34-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,5 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 80656-34:
(7*8)+(6*0)+(5*6)+(4*5)+(3*6)+(2*3)+(1*4)=134
134 % 10 = 4
So 80656-34-4 is a valid CAS Registry Number.

Deconjugation of dehydroamino acids: Stereoselective synthesis of racemic (E)-vinylglycines

Alexander, Paul A.,Marsden, Stephen P.,Munoz Subtil, Dulce M.,Reader, John C.

, p. 5433 - 5436 (2007/10/03)

(Chemical Equation Presented) A practical and general two-step synthesis of carbamate-protected (E)-vinylglycines from aliphatic aldehydes is reported. The key step involves the kinetic α-protonation of dianionic dienolates derived from dehydroamino acids

A flexible synthesis of azasugars and homoazasugars via olefin metathesis

Huwe, Christoph M.,Blechert, Siegfried

, p. 61 - 67 (2007/10/03)

A flexible synthesis of azasugars and homoazasugars from vinyl glycine methyl ester is described. The syntheses, which are based on ring closing olefin metathesis steps and stereocontrolled functionalizations of the formed double bonds, offer a broad vari

Structure and Stereochemistry of Three Phytotoxins, Syringomycin, Syringotoxin and Syringostatin, Produced by Pseudomonas syringae pv. syringae

Fukuchi, Naoyuka,Isogai, Akira,Nakayama, Jiro,Takayama, Seiji,Yamashita, Shuichi,et al.

, p. 1149 - 1158 (2007/10/02)

The structures of two phytotoxins, syringomycin and syringotoxin, produced by Pseudomonas syringae pv. syringae, were determined.Several amino acid residues of syringomycin were different from those in the syringostatins.Syringotoxin B proved to be syringostatin A.The three kinds of phytotoxins showed close structural similarity, and the stereochemistry of their components was deduced and compared.
