132819-80-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 132819-80-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,8,1 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 132819-80:
(8*1)+(7*3)+(6*2)+(5*8)+(4*1)+(3*9)+(2*8)+(1*0)=128
128 % 10 = 8
So 132819-80-8 is a valid CAS Registry Number.

Palladium-catalyzed oxidative heck-type allylation of β,β- disubstituted enones with allyl carbonates

Jin, Weiwei,Yang, Qin,Wu, Ping,Chen, Jiping,Yu, Zhengkun

, p. 2097 - 2102 (2014/07/07)

The palladium-catalyzed oxidative Heck-type allylation of β,β-disubstituted enones, i.e., α-oxoketene dithioacetals, was efficiently realized with allyl carbonates, providing a concise route to highly functionalized dienes. The present synthetic methodology utilizes the substrate activation strategy to activate the C-H bond of β,β-disubstituted enones by introduction of a 1,2-dithiolane functionality to make the enone substrate highly polarized and thus increase its reactivity, demonstrating rare examples for transition metal-catalyzed allylic substitution of ss,ss-disubstituted enones through a Heck-type allylation process.
