105755-44-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 105755-44-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,7,5 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 105755-44:
(8*1)+(7*0)+(6*5)+(5*7)+(4*5)+(3*5)+(2*4)+(1*4)=120
120 % 10 = 0
So 105755-44-0 is a valid CAS Registry Number.

Complexation of Methyl Orange and Tropaeolin 000 No. 2 by β-cyclodextrin dimers

Haskard, Carolyn A.,May, Bruce L.,Kurucsev, Tomas,Lincoln, Stephen F.,Easton, Christopher J.

, p. 279 - 282 (2007/10/03)

Spectrophotometric studies of the complexation of Methyl Orange (MO-) and Tropaeolin 000 No. 2 (TR-) anions by dimeric N,N′-bis(6A-deoxy-6A-β-cyclodextrin)urea (βCD)2ur and its oxalamide and succinamide analogues, (βCD)2ox and (βCD)2su, respectively, are consistent with the predominant formation of complexes of the general formulae (βCD)2x·MO- characterized by stability constants K1 = (1.05 ± 0.04) × 105, (1.92 ± 0.04) × 105 and (2.50 ± 0.02) × 104 dm3 mol-1 and (βCD)2x·TR- characterized by K1 = (1.39 ± 0.03) × 104, (7.4 ± 0.1) × 103 and (4.60 ± 0.05) × 103 dm3 mol-1, in aqueous phosphate buffer at pH 9.0 and 5.5 and 298.2 K. These values are significantly greater than K1 = 2160 and 710 dm3 mol-1 for the β-cyclodextrin complexes, βCD·MO- and βCD·TR- and are indicative of cooperative binding in (βCD)2x·MO- and (βCD)2x·TR-. The factors affecting complex stability are discussed and comparisons are made with related systems.

Comparison of the Proton-transfer Behaviour of 4-(2,4-Dihydroxyphenylazo)- and 4-(2-Hydroxy-1-naphthylazo)-benzenesulphonates

Hibbert, Frank,Simpson, Gareth R.

, p. 985 - 990 (2007/10/02)

A linear dependence of rate on hydroxide ion concentration has been observed for removal of the intramolecularly hydrogen-bonded proton from 4-(2-hydroxy-1-naphthylazo)benzenesulphonate (2), in contrast to the copmplex rate dependence found for 4-(2,4-dihydroxyphenylazo)benzenesulphonate (1).Possible explanations are considered.The magnitude of the kinetic solvent isotope effect and the observation of general base catalysis in proton removal from (2) are discussed.
