109665-87-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 109665-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,6,6 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 109665-87:
(8*1)+(7*0)+(6*9)+(5*6)+(4*6)+(3*5)+(2*8)+(1*7)=154
154 % 10 = 4
So 109665-87-4 is a valid CAS Registry Number.

A Mechanistic Change in the Alkaline Hydrolysis of Esters of Fluorene-9-carboxylic Acid

Alborz, Manoochehr,Douglas, Kenneth T.

, p. 728 - 729 (1980)

The Broensted leaving group (βlg) plot for the alkaline hydrolysis of fluorene-9-carboxylate esters in the pH region corresponding to the existence of the ester anion shows a minimum flanked by a region of high negative βlg (-1.01), corresponding to an E1cb pathway and, for esters of pKlg >9.5, a region of positive βlg (+0.11).

Electrostatic micellar effects on the rate of spontaneous decomposition of m-nitrophenyl 9-fluorenecarboxylate

Correia, Valdir R.,Cuccovia, Iolanda Midea,Stelmo, Magaly,Chaimovich, Hernan

, p. 2144 - 2146 (1992)

The effects of neutral, ionic, and zwitterionic micelles on the rate of the spontaneous decomposition of m-nitrophenyl 9-fluorenecarboxylate (I) were determined. Neutral micelles of a poly(oxyethylene) detergent produce a small increase in the decomposition rate. Negatively charged micelles of sodium dodecyl sulfate catalyze the reaction 2-fold while positively charged micelles of hexadecyltrimethylammonium bromide (CTAB) inhibit by a similar factor. Micelles of N-hexadecyl-N,N-dimethylammonium 3-propanesulfonate inhibit the decomposition of I to a larger extent than those of O-hexadecyl-phosphorylcholine while lysolecithin micelles do not affect the reaction rate. Thus, charge orientation of the monomer does not determine the kinetic effects of zwitterionic micelles on the rate of decomposition of I. The rate modifications produced by micelles on this reaction are consistent with electrostatic effects on the relative energies of initial and transition states.
