74461-32-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74461-32-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,6 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74461-32:
(7*7)+(6*4)+(5*4)+(4*6)+(3*1)+(2*3)+(1*2)=128
128 % 10 = 8
So 74461-32-8 is a valid CAS Registry Number.

Oxatriaza Macrocyclic Ligands: Studies of Protonation and Metal Complexation

Amorim, Maria Teresa S.,Chaves, Silvia,Delgado, Rita,Silva, Joao J. R. Frausto da

, p. 3065 - 3072 (2007/10/02)

Some 12- to 14-membered oxatriaza macrocyclic ligands and their methylated derivatives have been synthesised and their protonation studied by potentiometric and 1H NMR techniques.The stability constants of the complexes formed by these ligands with severa

MACROHETEROCYCES. XXXVI. A CONVENIENT METHOD FOR SYNTHESIS OF DI- AND POLYAZACROWN ETHERS

Luk'yanenko, N.G.,Basok, S.S.,Filonova, L.K.

, p. 1562 - 1571 (2007/10/02)

A method is proposed for the production of di- and polyazacrown ethers by the condensation of bissulfonamides with dibromides or ditosyloxy derivatives in a two-phase aqueous alkali-toluene (benzene) system.The optimum concentration range for the substrate and the alkylating agent is 0.017-0.1 M.The catalytic activity of the quaternary ammonium salts decreases in the order (Bu)4NI > (Bu4)NBr > (Bu4)NCl > (Bu4)NHSO4 > (C2H5)3C6H5CH2NCl >> (Et)4NI > (Et)4NBr.The highest yields of te 12-membered azacrown ethers are obtained in the presence of lithium hyroxide, and the largest yields of the crown ethers with larger ring sizes are obtained in the presence of sodium or potassium hydroxide, and this is probably due to the matrix effects of the cation.
