198760-84-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 198760-84-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,7,6 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 198760-84:
(8*1)+(7*9)+(6*8)+(5*7)+(4*6)+(3*0)+(2*8)+(1*4)=198
198 % 10 = 8
So 198760-84-8 is a valid CAS Registry Number.

Penicillin G acylase mediated synthesis of the enantiopure (S)-3-amino-azetidinl-2-one

Cainelli, Gianfranco,Giacomini, Daria,Galletti, Paola,DaCol, Marco

, p. 3231 - 3235 (1997)

A detailed study of the influence of temperature, pH and enzyme amount on the enantiomeric excess in the enzymatic resolution of N-1 protected 3-amino-azetidin-2-ones with supported PGA is presented. Both enantiomers could be obtained in good enantiomeric

Temperature and solvent effects on enzyme stereoselectivity: Inversion temperature in kinetic resolutions with lipases

Cainelli,De Matteis,Galletti,Giacomini,Orioli

, p. 2351 - 2352 (2007/10/03)

Eyring plots of InE vs. 1/T show inversion temperature in kinetic resolution by lipases, demonstrating that clustering effects in the substrate solvation manage the enzymatic selectivity.
