Check Digit Verification of cas no

The CAS Registry Mumber 224311-55-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,4,3,1 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 224311-55:
(8*2)+(7*2)+(6*4)+(5*3)+(4*1)+(3*1)+(2*5)+(1*5)=91
91 % 10 = 1
So 224311-55-1 is a valid CAS Registry Number.

Novel electron-rich bulky phosphine ligands facilitate the palladium-catalyzed preparation of diaryl ethers

Aranyos, Attila,Old, David W.,Kiyomori, Ayumu,Wolfe, John P.,Sadighi, Joseph P.,Buchwald, Stephen L.

, p. 4369 - 4378 (2007/10/03)

A general method for the palladium-catalyzed formation of diaryl ethers is described. Electron-rich, bulky aryldialkylphosphine ligands, in which the two alkyl groups are either tert-butyl or 1-adamantyl, are the key to the success of the transformation. A wide range of electron-deficient, electronically neutral and electron-rich aryl bromides, chlorides, and triflates can be combined with a variety of phenols with the use of sodium hydride or potassium phosphate as base in toluene at 100 °C. The bulky yet basic nature of the phosphine ligand is thought to be responsible for increasing the rate of reductive elimination of the diaryl ether from palladium.
