2570-41-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2570-41-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,7 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2570-41:
(6*2)+(5*5)+(4*7)+(3*0)+(2*4)+(1*1)=74
74 % 10 = 4
So 2570-41-4 is a valid CAS Registry Number.

AN ELECTRON SPIN RESONANCE INVESTIGATION OF THE RADICAL CATIONS FROM POLY(ALKYLTHIO)BENZENES

Alberti, Angelo,Pedulli, Gian Franco,Tiecco, Marcello,Testaferri, Lorenzo,Tingoli, Marco

, p. 975 - 980 (2007/10/02)

The radical cations of some poly(methylthio)- and poly(isopropylthio)-benzenes have been investigated by e.s.r. spectroscopy.Discrimination between the couplings due to the aryl and alkyl protons, when the assignment is not straightforward, has been made

Reactions of Polychlorobenzenes with Alkanethiol Anions in HMPA. A Simple, High-Yield Synthesis of Poly(alkylthio)benzenes

Testaferri, Lorenzo,Tingoli, Marco,Tiecco, Marcello

, p. 4376 - 4380 (2007/10/02)

Reactions of the isomeric trichlorobenzenes and tetrachlorobenzenes and of pentachloro- and hexachlorobenzene with an excess of the sodium salt of the isopropanethiol, in HMPA, afforded the products of complete displacement of all the chlorine atoms present in the molecule.Similar substitutions were also obtained with EtSNa.The reactions with MeSNa were in some cases complicated by the competitive nucleophilic attack at the methyl group of the initially formed aryl methyl thioethers which are thus demethylated to afford thiophenols.
