97634-15-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 97634-15-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,6,3 and 4 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 97634-15:
(7*9)+(6*7)+(5*6)+(4*3)+(3*4)+(2*1)+(1*5)=166
166 % 10 = 6
So 97634-15-6 is a valid CAS Registry Number.

Steric effects which determine the conformational preferences and stereodynamic processes of aryl fluorenyl ketones

Casarini, Daniele,Lunazzi, Lodovico,Mazzanti, Andrea

supporting information; experimental part, p. 1619 - 1626 (2009/06/27)

The stereodynamic processes and conformational preferences of two classes of aryl fluorenyl ketones have been investigated by means of dynamic NMR spectroscopy, DFT calculations and X-ray diffraction. When the aryl substituent has two hydrogens in the ortho positions, its rotation is independent of that of the fluorene ring. In contrast, if the two ortho hydrogens are replaced by the bulkier methyl groups (e.g. mesityl fluorenyl ketones), the motion of the aryl ring interacts with the fluorene, and the two rings rotate in a correlated manner.
