Check Digit Verification of cas no
The CAS Registry Mumber 29920-02-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,9,2 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 29920-02:
(7*2)+(6*9)+(5*9)+(4*2)+(3*0)+(2*0)+(1*2)=123
123 % 10 = 3
So 29920-02-3 is a valid CAS Registry Number.

Bilayer Membranes of Triple-Chain Ammonium Amphiphiles
Kunitake, Toyoki,Kimizuka, Nobuo,Higashi, Nobuyuki,Nakashima, Naotoshi
, p. 1978 - 1983 (2007/10/02)
Ten ammonium amphiphiles which possess three long-chain alkyl tails (C12 or C16) were prepared.They form clear aqueous dispersions upon sonication.Electron microscopy and light scattering experiments indicated the formation of huge bilayer aggregates except for one case.These bilayers undergo the characteristic crystal-to-liquid crystal-phase transition, as confirmed by differential scanning calorimetry (DSC) and by fluorescence depolarization of a diphenylhexatriene probe.Riboflavin, a water-soluble fluorescent probe, was shown to be trapped in bilayer vesicles of some triple-chain amphiphiles.Mixing of these bilayers with those of single-chain and double-chain amphiphiles was examined by DSC and by absorption spectroscopy.Together with our previous results, the present study establishes that the bilayer formation is a general phenomenon that is observable for a wide variety of synthetic amphiphiles.
