Check Digit Verification of cas no
The CAS Registry Mumber 18276-53-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,2,7 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 18276-53:
(7*1)+(6*8)+(5*2)+(4*7)+(3*6)+(2*5)+(1*3)=124
124 % 10 = 4
So 18276-53-4 is a valid CAS Registry Number.

Palladium catalysed C-N bond formation in supercritical carbon dioxide has been accomplished. Carbamic acid formation is avoided in part through the use of an N-silylamine as the coupling partner. Employing a catalyst system of Pd 2dba3 (1 mol%) and 2-dicyclohexylphosphino-2′, 4′,6′-triisopropyl-1,1′-biphenyl (X-Phos) (2 mol%) enabled the catalytic amination of aryl bromides and chlorides with N-silylanilines to be realised in excellent yield. Extension of the methodology to the N-arylation of N-silyldiarylamines, N-silylazoles and N-silylsulfonamides is reported. The Royal Society of Chemistry 2005.
