Check Digit Verification of cas no

The CAS Registry Mumber 1191-50-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,9 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1191-50:
(6*1)+(5*1)+(4*9)+(3*1)+(2*5)+(1*0)=60
60 % 10 = 0
So 1191-50-0 is a valid CAS Registry Number.

The association of an ionic surfactants with β-cyclodextrin. An isothermal titration calorimeter study

Eli, Wumanjiang,Chen, Wenhai,Xue, Qunji

, p. 1283 - 1296 (1999)

The association of a series of anionic surfactants (CnH2n+1SO4Na, n = 6, 8, 10, 12, 14) with β-cyclodextrin was studied by means of the isothermal titration calorimeter (i.t.c.) at T = 298.15 K. For these types of inclusion complexes, the results agreed well with a 1:1 association mode. Apparent values for the association constants, and changes in the standard molar Gibbs energies, enthalpies, and entropies were derived for the association process. The results indicated that the association of surfactants with β-cyclodextrin is characterized by both favourable enthalpy and favourable entropy changes. The results also demonstrated that the longer the alkyl chain of the anionic surfactant, the greater the association constant with β-cyclodextrin.

Influence of Chain Length on the Sphere-to-Rod Transition in Alkyl Sulfate Micelles

Missel, Paul J.,Mazer, Norman A.,Benedek, George B.,Carey, Martin C.

, p. 1264 - 1277 (2007/10/02)

Using Quasielastic light scattering spectroscopy (QLS) we have deduced the mean hydrodynamic radius (Rh) of alkyl sulfate micelles as functions of chain length (number of carbons nc = 8-16), temperature (0-85 deg C), detergent concentration (0.01-4g/dL), and NaCl concentration (0.1-2 M).In the region of low chain length (nc h values (extrapolated to the cmc) increase approximately linearly with the chain length.These results combained with Huisman's aggregation numbers (nw(cmc)) are consistent with a micellar shape that is close to spherical (axial ratio less than 2).Under conditions of high NaCl concentrations of high NaCl concentration the micelles exhibit a temperature-dependent growth from small spherical aggregates into long spherocylindrical micelles at concentrations above the cmc.With increasing chain length the temperature dependence of Rh becomes stronger and the NaCl and detergent concentrations needed for micellar growth become smaller.Light scattering intensity measurements confirm a rodlike growth for these micelles at all chain lengths.From these Rh measurements, values of the thermodynamic parameter K governing the sphere-to-rod transition are determined by using an extension of our previous thermodynamic model (Missel et al., J.Phys.Chem., 84, 1044 (1980)).A quantitative analysis of the dependence of K on chain length, temperature, and NaCl concentration provides new insights into energetic factors which govern the structure and growth of micelles.
