214492-04-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 214492-04-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,4,4,9 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 214492-04:
(8*2)+(7*1)+(6*4)+(5*4)+(4*9)+(3*2)+(2*0)+(1*4)=113
113 % 10 = 3
So 214492-04-3 is a valid CAS Registry Number.

Conformational control in the SuperQuat chiral auxiliary 5,5-dimethyl-4-iso-propyloxazolidin-2-one induces the iso-propyl group to mimic a tert-butyl group

Bull,Davies,Key,Nicholson,Savory

, p. 1721 - 1722 (2000)

1H NMR nOe spectroscopic studies reveal that conformational control in the enolates of N-acyl-5,5-dimethyl-4-iso-propyloxazolidin-2-ones ensures that the stereodirecting effect of its 4-iso-propyl-5,5-dimethyl functional group affords superior levels of facial selectivity normally associated with enolates derived from N-acyl-4-tert-butylox-azolidin-2-ones.

Probing the resolution of 2-phenylpropanoyl chloride using quasi-enantiomeric Evans' oxazolidinones

Coumbarides, Gregory S.,Eames, Jason,Flinn, Anthony,Northen, Julian,Yohannes, Yonas

, p. 849 - 853 (2007/10/03)

The parallel kinetic resolution of 2-phenylpropanoyl chloride using quasi-enantiomeric oxazolidinones is discussed. The levels of diastereoselectivity were found to be dependent on the presence of an additional (quasi)-enantiomeric oxazolidinone and its s
