Check Digit Verification of cas no

The CAS Registry Mumber 2209-90-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,0 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2209-90:
(6*2)+(5*2)+(4*0)+(3*9)+(2*9)+(1*0)=67
67 % 10 = 7
So 2209-90-7 is a valid CAS Registry Number.

Neutral Ligands with Surfactant-Type Structure - Synthesis, Complexation, and Ion Transfer

Weber, Edwin

, p. 770 - 801 (2007/10/02)

New lipophilic neutral ligands which combine crown ether and podand characteristics with structural features of surfactants (cf. formulas 1-12, 16-26) were synthesized.Their complexation behaviour was studied, their solid-to-liquid and liquid-to-liquid phase transfer properties as well as their efficiency in ion transport across a liquid model membrane.Crystalline stoichiometric complexes of the cycles 2a-4a and of 3e with NaSCN, Ba(SCN)2, and BaI2 can be isolated.Among the noncyclic representatives a crystalline complex is obtained only from 11 with BaI2.The ligand 8d behaves in aqueous solution as a typical surfactant showing micelle formation and cloud point.
