223575-99-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 223575-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,5,7 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 223575-99:
(8*2)+(7*2)+(6*3)+(5*5)+(4*7)+(3*5)+(2*9)+(1*9)=143
143 % 10 = 3
So 223575-99-3 is a valid CAS Registry Number.

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.
