454451-67-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 454451-67-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,4,4,5 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 454451-67:
(8*4)+(7*5)+(6*4)+(5*4)+(4*5)+(3*1)+(2*6)+(1*7)=153
153 % 10 = 3
So 454451-67-3 is a valid CAS Registry Number.

Asymmetric synthesis of nitrogen heterocycles by reaction of chiral β-enaminocarbonyl substrates with acrylate derivatives

Agami, Claude,Dechoux, Luc,Hebbe, Séverine

, p. 2521 - 2523 (2002)

We have studied the reactivity of β-enaminoesters 1 (R2=OMe) or β-enaminoketone 1 (R2=Me), derived from (S)-phenylglycinol, with activated acrylate derivatives. Substrates 1 (R1=Me) afforded by aza-annulation oxazololactam

A novel stereocontrolled synthesis of enantiopure bicyclic lactams

Agami, Claude,Dechoux, Luc,Hebbe, Séverine

, p. 5311 - 5313 (2007/10/03)

A study on the reactivity of 3,4-dihydro-2-pyridones 9, derived from (S)-phenylglycinol, toward different bases is presented. Using a catalytic amount of bases, the cis bicyclic lactams were obtained with excellent diastereoselectivities.
