97538-61-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97538-61-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,5,3 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 97538-61:
(7*9)+(6*7)+(5*5)+(4*3)+(3*8)+(2*6)+(1*1)=179
179 % 10 = 9
So 97538-61-9 is a valid CAS Registry Number.

OPTICAL ACTIVITY OF LACTONES AND LACTAMS-III CIRCULAR DICHROISM SPECTRA OF 5-OXAZOLIDINONES
Polonski, T.
, p. 603 - 610 (2007/10/02)
The synthesis and chiroptical properties of several 5-oxazolidinones derived from α-amino acids are reported.The existence of an equilibrium between the two enantiomeric envelope conformations of 5-membered ring has been inferred from CD and NMR spectra.I
