5520-39-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5520-39-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,2 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5520-39:
(6*5)+(5*5)+(4*2)+(3*0)+(2*3)+(1*9)=78
78 % 10 = 8
So 5520-39-8 is a valid CAS Registry Number.

Palladium-mediated functionalization of heteroaromatic cations: Comparative study on quinolizinium cations

Garcia-Cuadrado, Domingo,Cuadro, Ana M.,Barchin, Bernardo M.,Nunez, Ana,Caneque, Tatiana,Alvarez-Builla, Julio,Vaquero, Juan J.

, p. 7989 - 7995 (2007/10/03)

An efficient palladium-catalyzed cross-coupling reaction on heteroaromatic cations is described. A comparative study of the Stille and Suzuki reactions shows that only the Stille reaction is able to produce an efficient C-C bond formation between any of the four isomeric bromoquinolizinium bromides and a variety of stannanes. In the presence of the catalysts Pd(PPh3)4 or Pd2(dba)3P(o-Tol)3, vinyl, ethynyl, aryl, and heteroaryl groups are successfully incorporated into the quinolizinium system in satisfactory yields under mild reaction conditions. This procedure represents a marked improvement on the functionalization of this class of heteroaromatic cation.
