17570-85-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17570-85-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,5,7 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 17570-85:
(7*1)+(6*7)+(5*5)+(4*7)+(3*0)+(2*8)+(1*5)=123
123 % 10 = 3
So 17570-85-3 is a valid CAS Registry Number.

N-phenyl-N-(phenylthioxomethyl)benzamide

Fu, Tai Y.,Scheffer, John R.,Trotter, James

, p. 101 - 102 (1998)

The title molecule, C20H15NOS, adopts an (ES,ZO) conformation, similar to that of other monothioimides, with an intramolecular O...-C(S) contact of 2.821 (5) A; a photochemical cleavage reaction probably proceeds via intramolecular nucleophilic attack of oxygen on the C=S double bond in the presence of solvolytic agents.

CARBONSAEURE-IMIDSAEURE-THIOANHYDRIDE AUS THIOAMIDEN UND CARBONSAEURECHLORIDEN IM ZWEIPHASENSYSTEM FLUESSIG-FEST

Walter, Wolfgang,Saha, Chantu Ranjan

, p. 63 - 78 (2007/10/02)

By acylation of thioamides in a two phase system liquid-solid with acetone-NaOH the hitherto unknown S-acylderivatives of the thioamides are obtained which may be regarded as Carboxylic acid-imidic acid-thioanhydrides.Some compounds of the new class can b

Reaction of Mesoionic Thiazolones with m-Chloroperbenzoic Acid. Oxidative Dipole Extensions

Sheradsky, Tuvia,Zbaida, David

, p. 4850 - 4853 (2007/10/02)

The oxidation of anhydro-4-hydroxy-2,3,5-triarylthiazolium hydroxides (1) with m-chloroperbenzoic acid gave (in primary alcohols) 2,5-dialkoxy-2,3,5-triarylthiazolidin-4-ones (5) and N-aroylthiobenzanilides (6).Oxidation of anhydro-5-hydroxy-3-methyl-2-phenylthiazolium hydroxide (2) gave 3-methyl-2-phenylthiazolidine-4,5-dione (8) and N-formyl-N-methylthiobenzamide (9).The products arise from initial oxidations at the carbon atoms at position 5 of 1 and position 4 of 2, and transformation modes to the final products are discussed.These oxidations are the first examples of oxidative dipole extensions.
