72009-05-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 72009-05-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,0,0 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 72009-05:
(7*7)+(6*2)+(5*0)+(4*0)+(3*9)+(2*0)+(1*5)=93
93 % 10 = 3
So 72009-05-3 is a valid CAS Registry Number.

Nitroalkenes as electrophiles in the asymmetric Michael reaction involving chiral imines/enamino esters

Thominiaux, Cyrille,Rousse, Sebastien,Desmaele, Didier,D'Angelo, Jean,Riche, Claude

, p. 2015 - 2021 (2007/10/03)

Addition of 2-nitropropene to the chiral imine derived from 2- methylcyclopentanone and (S)-1-phenylethylamine furnished the expected Michael adduct. The latter compound was then efficiently converted into (R)- pentalenone through a Nef reaction. Condensa

3-Chloro-2-(trimethylsiloxy)-1-propene as an Electrophilic Acetonyl Equivalent. A Novel Regioselective Synthesis of 1,4-Dicarbonyl Compounds

Hosomi, Akira,Shirahata, Akihiko,Araki, Yoshitaka,Sakurai, Hideki

, p. 4631 - 4633 (2007/10/02)

α-Metalated imines, hydrazones, and activated methylene compounds are acetonylated with 3-chloro-2-(trimethylsiloxy)-1-propene in high yield.Highly regioselective acetonylation at either the tertiary or secondary α-carbon of 2-methylcyclohexanone can be carried out by selecting the reaction conditions.
