42383-63-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 42383-63-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,3,8 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 42383-63:
(7*4)+(6*2)+(5*3)+(4*8)+(3*3)+(2*6)+(1*3)=111
111 % 10 = 1
So 42383-63-1 is a valid CAS Registry Number.

Preparation of Optical Active 2-(Aryloxy)propionic Acids by Kinetic Resolution. - Herbizides

Salz, Ulrich,Ruechardt, Christoph

, p. 3457 - 3462 (2007/10/02)

2-(Aryloxy)propionic anhydrides 2 were transformed with 70-90percent stereoselectivity into the R,S- or S,R-diastereomeric esters 4, respectively, on reaction with stoichiometric amounts of optical active 1-(4-pyridyl)ethanol (3).The acid 1 set free in one mol equivalent during this reaction was mainly the other enantiomer in 62-72percent optical yields.By treatment with boiling acetic anhydride and pyridine the acid 1 is transformed back into racemic anhydride 2.The ester 4 was hydrolyzed with aqueous acid to optical active 1 with regeneration of the optical active alcohol 3.In this way a quantitative transformation of racemic acids 1 into that enantiomer which is an active herbizide is possible using 3 as optical active auxiliary material.
