Check Digit Verification of cas no

The CAS Registry Mumber 134420-93-2 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, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 134420-93:
(8*1)+(7*3)+(6*4)+(5*4)+(4*2)+(3*0)+(2*9)+(1*3)=102
102 % 10 = 2
So 134420-93-2 is a valid CAS Registry Number.

Practical, highly enantioselective chemoenzymatic one-pot synthesis of short-chain aliphatic β-amino acid esters

Wei?, Markus,Gr?ger, Harald

experimental part, p. 1251 - 1254 (2009/09/06)

A practical, highly enantioselective method for the synthesis of short-chain aliphatic β-amino acid esters was developed starting from prochiral and easily accessible substrates. This chemoenzymatic approach is based on a nonenzymatic aza-Michael addition

GABA-uptake inhibitors: Construction of a general pharmacophore model and successful prediction of a new representative

N'Goka,Schlewer,Linget,Chambon,Wermuth

, p. 2547 - 2557 (2007/10/02)

A model for the pharmacophore of GABA-uptake inhibitors was established using published structure-activity data and molecular modeling. The model accounted for the activities of different classes of GABA-uptake inhibitors. Analogues of guvacine substituted at position 6 were synthesized in order to confirm the model. 6-(3,3-Diphenylpropyl)guvacine (30f), which fit well with the pharmacophore, had an in vitro IC50 of 0.1 μM. This value is as good as those of the best GABA-uptake inhibitors known today.
