219598-78-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219598-78-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,5,9 and 8 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 219598-78:
(8*2)+(7*1)+(6*9)+(5*5)+(4*9)+(3*8)+(2*7)+(1*8)=184
184 % 10 = 4
So 219598-78-4 is a valid CAS Registry Number.

Pd-catalyzed synthesis of a tethered soluble polymeric phosphine ligand
Bergbreiter, David E.,Liu, Yun-Shan,Furyk, Steve,Case, Brenda L.
, p. 8799 - 8802 (1998)
The use of a Pd-catalyzed phosphine-aryl iodide coupling chemistry to prepare soluble polymeric phosphine ligands is described. The lack of sensitivity of the catalyst to the presence of excess phosphine ligand and the fact that the soluble polymeric phos
