Check Digit Verification of cas no

The CAS Registry Mumber 870194-10-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,0,1,9 and 4 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 870194-10:
(8*8)+(7*7)+(6*0)+(5*1)+(4*9)+(3*4)+(2*1)+(1*0)=168
168 % 10 = 8
So 870194-10-8 is a valid CAS Registry Number.

Palladium catalysed aryl amination reactions in supercritical carbon dioxide

Smith, Catherine J.,Tsang, Melanie W.S.,Holmes, Andrew B.,Danheiser, Rick L.,Tester, Jefferson W.

, p. 3767 - 3781 (2007/10/03)

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.
