Check Digit Verification of cas no
The CAS Registry Mumber 2390-68-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,9 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2390-68:
(6*2)+(5*3)+(4*9)+(3*0)+(2*6)+(1*8)=83
83 % 10 = 3
So 2390-68-3 is a valid CAS Registry Number.

Fluorescence Quenching in Double-Chained Surfactants. 1. Theory of Quenching in Micelles and Vesicles
Miller, D. D.,Evans, D. F.
, p. 323 - 333 (1989)
The time-resolved fluorescence quenching technique is used to investigate the aggregation behavior of double-chained surfactants.With a new extension of this technique, surfactant solutions consisting of (1) only vesicles, (2) mixtures of vesicles and micelles, or (3) only micelles can be distinguished.When applied to solutions of didodecyldimethylammonium acetate, the microstructure is determined to be composed of mainly small micelles over a wide concentration range (0.001-0.1 M); the contribution of vesicles to the total surfactant inventory is quite small.In studies of double-chained surfactants, the technique is particularly valuable for following the transformation of liquid crystalline dispersions to micellar solutions upon heating or dilution.

Didecyldimethylammonium tungstate has been designed as a balanced catalytic surfactant to form acidic three-liquid-phase microemulsion systems at room temperature in the presence of water, a non-chlorinated solvent and dimethyldioctylammonium salts (hydrogen sulfate and dihydrogen phosphate). The triphasic system is efficient for the oxidation of olefins, sulfides and thiophenes under mild conditions. Moreover, the recovery and reusability of the catalyst, the straightforward separation of products and catalysts in two distinct phases as well as the possible use of environmentally friendly solvents such as tert-butyl acetate, make this system particularly attractive for catalytic oxidation reactions involving hydrogen peroxide as the primary oxidant under acidic or neutral conditions.
