80089-36-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 80089-36-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,0,8 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 80089-36:
(7*8)+(6*0)+(5*0)+(4*8)+(3*9)+(2*3)+(1*6)=127
127 % 10 = 7
So 80089-36-7 is a valid CAS Registry Number.

Participation of a Neighboring Amide Group in the Hydrolytic C-OAr Cleavage of 1-Acyl-2-(2-phenoxyethyl)pyrrolidines

Dobrzeniecka, Regina

, p. 901 - 910 (2007/10/02)

Measurements are reported on the kinetics of acid-catalyzed hydrolysis of 1-acetyl- and 1-propionyl-2-(2-phenoxyethyl)pyrrolidine.The pseudo-first-order rate constants, kobs, were obtained: kobs = kA + kB, where kA and kB refer to the rate constants for the formation of 2-(2-phenoxyethyl)pyrrolidine A and 2-(2-hydroxyethyl)pyrrolidine B, respectively.Formation of the product B with consequent liberation of the phenol is attributed to the effect of neighboring amide group participation.A mechanism comprising a six-membered cyclic intermediate has been proposed for hydrolysis leading to cleavage of the ether bond.
