134149-25-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134149-25-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,1,4 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 134149-25:
(8*1)+(7*3)+(6*4)+(5*1)+(4*4)+(3*9)+(2*2)+(1*5)=110
110 % 10 = 0
So 134149-25-0 is a valid CAS Registry Number.

Cyclisation of ω-unsaturated β-dicarbonylcompounds catalyzed by a palladium hydride species
Monteiro,Balme,Gore
, p. 1645 - 1648 (2007/10/02)
When treated with potassium t-butoxide and then with a palladium(0) complex, the title compounds 1, 2, or 9 are smoothly cyclized by an attack of the enolates onto the unsaturation assisted by a palladium(II) species of tBuO-Pd-H type. The formation of a
