119092-11-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119092-11-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,0,9 and 2 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 119092-11:
(8*1)+(7*1)+(6*9)+(5*0)+(4*9)+(3*2)+(2*1)+(1*1)=114
114 % 10 = 4
So 119092-11-4 is a valid CAS Registry Number.

RESOLUTION AND DETERMINATION OF ENANTIOMERIC EXCESSES OF CHIRAL ALDEHYDES VIA CHIRAL IMIDAZOLIDINES
Mangeney, P.,Alexakis, A.,Normant, J. F.
, p. 2677 - 2680 (2007/10/02)
Enantiomeric purity of chiral aldehydes was determined by NMR analysis of derived imidazolidines.The diastereomeric imidazolidines were easily separated by silica gel column and converted into enantiomerically pure aldehyde by acid hydrolysis.
