Uses
Hexaethylene glycol dimethyl ether is a useful stationary phase in gas chromatographic analysis, and also suitable for the analysis of aqueous solutions.
Check Digit Verification of cas no
The CAS Registry Mumber 1072-40-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,7 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1072-40:
(6*1)+(5*0)+(4*7)+(3*2)+(2*4)+(1*0)=48
48 % 10 = 8
So 1072-40-8 is a valid CAS Registry Number.

AFFINITIES OF CROWN ETHERS, GLYMES, AND POLYAMINES FOR ALKALI PICRATES IN TOLUENE. APPLICATION OF POLYMER-SUPPORTED LINEAR POLYETHERS.

This work reports the measurements of K values for polyamines, glymes, a few glycols (including that of a long-chain polyethylene glycol, carbowax 6000), and some frequently used cation-binding ligands as complexers of lithium or sodium picrate in toluene as solvent. K values for different resins obtained with the same soluble ligand provide a comparison of the effectiveness of these resins in binding ionic solutes.
