75507-17-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 75507-17-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,0 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 75507-17:
(7*7)+(6*5)+(5*5)+(4*0)+(3*7)+(2*1)+(1*7)=134
134 % 10 = 4
So 75507-17-4 is a valid CAS Registry Number.

LIPOPHILIC BIS(CROWN ETHER) DERIVATIVES OF 15-CROWN-5 AND 18-CROWN-6 AS NEUTRAL CARRIERS OF ION-SELECTIVE ELECTRODES

Kimura, Keiichi,Ishikawa, Atsuo,Tamura, Hiroshi,Shono, Toshiyuki

, p. 447 - 450 (1984)

Lipophilic bis(crown ethers) containing 15-crown-5 and 18-crown-6 rings were synthesized so as to obtain excellent neutral carriers for K+- and Cs+-selective electrodes, respectively.The K+-selective electrode based on the dodecylmethylmalonate of bis(15-crown-5), (I) (n = 1, R = Me), exhibited eminent electrode properties, proving of great practical use, while the Cs+-selective electrode of the bis(18-crown-6) derivative (I) (n = 2, R = Me) did not give results as good as expected.The electrochemical selectivities of the K+ electrode based on the dodecylmalonate of bis(15-crown-5), (I) (n = 1, R = H), and octadecanoyloxymethyl-15-crown-5 (II) are also discussed.

Synthesis of lipophilic lariat ethers with pendant N-(X)sulfonyl carboxamide groups

Hu, Hui,Bartsch, Richard A.

, p. 557 - 562 (2007/10/03)

Synthetic routes to sixteen lipophilic lariat ether N-(X)sulfonyl carboxamides with X = trifluoromethyl, methyl, phenyl, and p-nitrophenyl are described. For this new family of proton-ionizable lariat ethers in which the acidity can be 'tuned' by X group variation, the ring size is systematically varied from 12-crown-4 to 14-crown-4 to 15-crown-5 to 18-crown-6.

Liquid-Liquid-Extraction of Metal Ions with Lariat Ethers

Gloe, K.,Muehl, P.,Beger, J.,Poeschmann, C.,Petrich, M.,Beyer, L.

, p. 413 - 421 (2007/10/02)

Lariat ethers of various ring size and substitution are synthesized and characterized by physical data and chemical analysis.The extraction behaviour of the crown compounds towards Na+, K+, Cs+ and Ag+ in a picric acid solution has been investigated.The extraction constants for 1:1 and 1:2 complexes are determined using the equilibrium distribution data.The results show that the flexible side chain in the investigated compounds has in no case a positive effect on the metal picrate extraction.
