Calculate Digit Verification of CAS Registry Number 672932-61:
(8*6)+(7*7)+(6*2)+(5*9)+(4*3)+(3*2)+(2*6)+(1*1)=185
185 % 10 = 5
So 672932-61-5 is a valid CAS Registry Number.

Palladium-Catalyzed Oxidative Alkoxylation of α-Alkenyl β-Diketones to Form Functionalized Furans

Han, Xiaoqing,Widenhoefer, Ross A.

, p. 1738 - 1740 (2007/10/03)

Treatment of 4-allyl-2,6-dimethyl-3,5-heptanedione with a catalytic amount of PdCl2(CH3CN)2 (5 mol %) and a stoichiometric amount of CuCl2 (2.2 equiv) in dioxane at 60 °C for 12 h formed 3-isobutyryl-2-isopropyl-5-methylfuran in 77% isolated yield. A number of α-alkenyl β-dike-tones underwent oxidative alkoxylation under these conditions to form 2,3,5-trisubsituted furans in moderate to good yield.
