Check Digit Verification of cas no

The CAS Registry Mumber 1259374-83-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,3,7 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1259374-83:
(9*1)+(8*2)+(7*5)+(6*9)+(5*3)+(4*7)+(3*4)+(2*8)+(1*3)=188
188 % 10 = 8
So 1259374-83-8 is a valid CAS Registry Number.

Synthesis of 2,4,5-trisubstituted thiazoles via lawesson's reagent-mediated chemoselective thionation-cyclization of functionalized enamides

Kumar, S. Vijay,Parameshwarappa,Ila

, p. 7362 - 7369 (2013/08/23)

An efficient route to 2-phenyl/(2-thienyl)-5-(het)aryl/(methylthio)-4- functionalized thiazoles via one-step chemoselective thionation-cyclization of highly functionalized enamides mediated by Lawesson's reagent is reported. These enamide precursors are obtained by nucleophilic ring-opening of 2-phenyl/(2-thienyl)-4-[bis(methylthio)/(methylthio)(het)arylmethylene] -5-oxazolones with alkoxides and a variety of primary aromatic/aliphatic amines or amino acid esters, leading to the introduction of an ester, an N-substituted carboxamide, or a peptide functionality in the 4-position of the product thiazoles.

Carbonates: Eco-friendly solvents for palladium-catalysed direct arylation of heteroaromatics

Dong, Jia Jia,Roger, Julien,Verrier, Cecile,Martin, Thibaut,Le Goff, Ronan,Hoarau, Christophe,Doucet, Henri

experimental part, p. 2053 - 2063 (2011/02/25)

The palladium-catalysed direct 2-, 4- or 5-arylation of a wide range of heteroaromatics with aryl halides proceed in moderate to good yields using the eco-friendly solvents carbonates. The best yields were obtained using benzoxazole or thiazole derivatives. The arylation of furan, thiophene, pyrrole, imidazole or isoxazole derivatives was found to require a more elevated reaction temperature. The Royal Society of Chemistry 2010.
