2183-83-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2183-83-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,8 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2183-83:
(6*2)+(5*1)+(4*8)+(3*3)+(2*8)+(1*3)=77
77 % 10 = 7
So 2183-83-7 is a valid CAS Registry Number.

Pd(0)-Catalyzed Direct Inter- And Intramolecular C-H Functionalization of 4-Carboxyimidazoles

Frippiat, Steven,Peresson, Antoine,Perse, Thibaut,Ramondenc, Yvan,Schneider, Cédric,Querolle, Olivier,Angibaud, Patrick,Poncelet, Virginie,Meerpoel, Lieven,Levacher, Vincent,Bischoff, Laurent,Baudequin, Christine,Hoarau, Christophe

supporting information, p. 1015 - 1021 (2020/06/17)

The palladium-catalyzed arylation and alkenylation of N -substituted methyl imidazole-4-carboxylates are described through inter- and intramolecular pathways. Both direct C2-H and C5-H arylation and alkenylation proceed under Pd(0)/Cu(I) cooperative catal

This invention is directed to compounds, which are PDE10A enzyme inhibitors. The invention provides a pharmaceutical composition comprising a therapeutically effective amount of a compound of the invention and a pharmaceutically acceptable carrier. The pr

Intramolecular homolytic substitution at the sulfur atom: an alternative way to generate phosphorus- and sulfur-centered radicals

Carta, Paola,Puljic, Nicolas,Robert, Carine,Dhimane, Anne-Lise,Ollivier, Cyril,Fensterbank, Louis,Lac?te, Emmanuel,Malacria, Max

experimental part, p. 11865 - 11875 (2009/04/06)

Two efficient procedures involving tin hydride or thiophenol-mediated intramolecular homolytic substitution at the sulfur atom are reported. They lead to the generation of varied P(V)-centered radicals from the corresponding aryl or alkyne thiophosphorus substrates. The radical formed can be trapped by an olefin via an intermolecular addition, leading to the construction of C-P bonds. Thiophosphination of triple bonds was also achieved using a radical cycloisomerization process. Extension of the methodology to sulfur-containing species was examined.
