Check Digit Verification of cas no

The CAS Registry Mumber 313697-17-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,3,6,9 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 313697-17:
(8*3)+(7*1)+(6*3)+(5*6)+(4*9)+(3*7)+(2*1)+(1*7)=145
145 % 10 = 5
So 313697-17-5 is a valid CAS Registry Number.

Copper- and Cobalt-Catalyzed Syntheses of Thiophene-Based Tertiary Amines

Bouarfa, Salima,Gra?l, Simon,Ivanova, Maria,Langlais, Timothy,Bentabed-Ababsa, Ghenia,Lassagne, Frédéric,Erb, William,Roisnel, Thierry,Dorcet, Vincent,Knochel, Paul,Mongin, Florence

, p. 3244 - 3258 (2019)

Thienylzinc halides and related compounds prepared by deprotonation followed by transmetalation were used in copper-catalyzed amination using N-benzoyloxy secondary amines. By extending the reaction to 1,5-naphthyridine, it was showed that the competitive dimer formation observed in the case of thiophenes was linked with the low stability of some thienylamines rather than homocoupling. Interestingly, thienylzinc halides and related compounds prepared by transmetalation of thienylmagnesium halides, either prepared from their bromo-precursors or generated by deprotometalation, were satisfactorily employed in cobalt-catalyzed aminations. Finally, aminothiophenes were involved in copper-catalyzed mono- and di-N-arylations, affording differently substituted di- and triphenylamines.

An advantageous synthesis of new indazolone and pyrazolone derivatives

Correa, Arkaitz,Tellitu, Imanol,Domínguez, Esther,SanMartin, Raul

, p. 11100 - 11105 (2007/10/03)

The synthesis of new indazolone and pyrazolone derivatives starting from methyl anthranilate type substrates is presented. This general approach constitutes a novel and advantageous alternative for the synthesis of the target heterocycles, which implies the use of the environmentally friendly oxidizer PIFA. The synthetic design includes the oxidation of N-arylamides by the hypervalent iodine reagent to the corresponding N-acylnitrenium ions, which can be intramolecularly trapped by an amine moiety to furnish the title compounds by formation of a new N-N single bond.
