Check Digit Verification of cas no

The CAS Registry Mumber 87117-66-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,1,1 and 7 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 87117-66:
(7*8)+(6*7)+(5*1)+(4*1)+(3*7)+(2*6)+(1*6)=146
146 % 10 = 6
So 87117-66-6 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.
