Check Digit Verification of cas no

The CAS Registry Mumber 133007-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,0,0 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 133007-77:
(8*1)+(7*3)+(6*3)+(5*0)+(4*0)+(3*7)+(2*7)+(1*7)=89
89 % 10 = 9
So 133007-77-9 is a valid CAS Registry Number.

1-Aminocyclopentane-1,2,4-tricarboxylic acids screening on glutamatergic and serotonergic systems

Gelmi, Maria Luisa,Caputo, Francesco,Clerici, Francesca,Pellegrino, Sara,Giannaccini, Gino,Betti, Laura,Fabbrini, Laura,Schmid, Lara,Palego, Lionella,Lucacchini, Antonio

, p. 7581 - 7589 (2008/04/05)

Enantiopure constrained 1-aminocyclopentane-1,2,4-tricarboxylic acids containing the glutamic acid skeleton were prepared as two diastereomers characterized by having the carboxylic groups in position two and four cis-oriented to each other and trans with respect to 1-carboxylic group and all cis-oriented carboxylic groups, respectively. A biochemical screening of activity of the above amino acids was investigated on glutamate and 5-HT receptors to find a possible metabotropic agonist, acting on the serotoninergic system.

The Diels-Alder reactions of polymer bound dehydroalanine derivatives

Burkett, Brendan A.,Chai, Christina L. L.

, p. 7035 - 7038 (2007/10/03)

The synthesis and Diels-Alder cycloadditions of a number of polymer bound dehydroalanine derivatives are described. The studies compare methodologies for accessing polymer bound dehydroalanines and establish the versatility and efficiency of solid phase Diels-Alder reactions in the synthesis of carbocyclic amino acids. These studies nicely complement the growing repertoire of methodologies for the functionalisation of amino acid derivatives.

ASYMMETRIC SYNTHESIS OF CYCLOALIPHATIC α-AMINO ACIDS WITH A NORBORNANE SKELETON

Cativiela, Carlos,Lopez, Pilar,Mayoral, Jose A.

, p. 379 - 388 (2007/10/02)

The asymmetric synthesis of endo and exo 2-aminonorbornane-2-carboxylic acids is carried out via the Diels-Alder reaction between cyclopentadiene and (-)-menthyl N-acetyl-α,β-dehydroalaninate.It is shown that this dienophile is more reactive than the corresponding methyl ester, which opens the way for the use of chiral N-acetyl-α,β-dehydroalaninates as dienophiles in asymmetric Diels-Alder reactions.As high diastereofacial selectivity is obtained with what was previously considered a mediocre chiral auxiliary, the acetamido group must play an important role, which is discussed.
