Check Digit Verification of cas no

The CAS Registry Mumber 221910-19-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,9,1 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 221910-19:
(8*2)+(7*2)+(6*1)+(5*9)+(4*1)+(3*0)+(2*1)+(1*9)=96
96 % 10 = 6
So 221910-19-6 is a valid CAS Registry Number.

Palladium-assisted multicomponent synthesis of 2-aryl-4-aminoquinolines and 2-aryl-4-amino[1,8]naphthyridines

Abbiati, Giorgio,Arcadi, Antonio,Canevari, Valentina,Capezzuto, Luca,Rossi, Elisabetta

, p. 6454 - 6460 (2005)

A palladium-mediated multicomponent domino reaction leading to 2-aryl-4-amino-quinolines and 2-aryl-4-amino[1,8]naphthyridines is reported. The scope of the reaction was examined using carbon monoxide, two 2-ethynyl-arylamines, four aryl iodides, and 10 primary amines as substrates. The selection of the appropriate catalytic system was achieved testing several palladium/phosphine systems and overrides previously reported drawbacks associated with the use of primary amines in related reactions. Moreover several features concerning the role of both palladium [(0) and (II)] and phosphines are reported.

Solvent-Dependent Cyclization of 2-Alkynylanilines and ClCF2COONa for the Divergent Assembly of N-(Quinolin-2-yl)amides and Quinolin-2(1 H)-ones

Wang, Ya,Zhou, Yao,Ma, Xingxing,Song, Qiuling

supporting information, p. 5599 - 5604 (2021/08/01)

Herein, we present an expedient Cu-catalyzed [5 + 1] cyclization of 2-alkynylanilines and ClCF2COONa to divergent construction of N-(quinolin-2-yl)amides and quinolin-2(1H)-ones by regulating the reaction solvents. Notably, nitrile acts as a solvent and performs the Ritter reactions. ClCF2COONa is used as a C1 synthon in this transformation, which also represents the first example for utilization of ClCF2COONa as an efficient desiliconization reagent. The current protocol involves in situ generation of isocyanide, copper-activated alkyne, Ritter reaction and protonation.

Copper(I)-Mediated Cascade Annulation via Dual C-H/C-H Activation: Access to Benzo[a]carbazolic AEEgens

Khandelia, Tamanna,Ghosh, Subhendu,Panigrahi, Pritishree,Shome, Rajib,Ghosh, Siddhartha Sankar,Patel, Bhisma K.

, p. 16948 - 16964 (2021/12/02)

A Cu(I)-mediated cascade cyclization/annulation of unprotectedo-alkynylanilines with maleimides in one pot is developed. The protocol offers sequential formation of one C-N and two C-C bonds to deliver fused benzo[a]carbazoles having free NH skeletons. The annulated products display fluorescence emission in the range of 485-502 nm with a large Stokes shift and fluorescence lifetime of ~17 ns. The annulated3aadisplays AEE behavior in the ethanol/hexane system and possesses marigold-flower-like morphology at the aggregated state. Cell viability assays enumerate biocompatible AEEgens, while their high intracellular fluorescence depicts cell imaging applicability.
