Calculate Digit Verification of CAS Registry Number 1334172-47:
(9*1)+(8*3)+(7*3)+(6*4)+(5*1)+(4*7)+(3*2)+(2*4)+(1*7)=132
132 % 10 = 2
So 1334172-47-2 is a valid CAS Registry Number.

Pd/C-Catalyzed coupling and cyclization of β-bromo-α,β- unsaturated carboxylic acids with terminal alkynes leading to alkylidenefuranones

Cho, Chan Sik,Kim, Hyo Bo

, p. 3264 - 3267 (2011)

Palladium-catalyzed coupling of β-bromo-α,β-unsaturated carboxylic acids with terminal alkynes and subsequent regioselective 5-exo-dig cyclization produces (Z)-alkylidenefuranones in good yields.
