81454-09-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81454-09-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,5 and 4 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81454-09:
(7*8)+(6*1)+(5*4)+(4*5)+(3*4)+(2*0)+(1*9)=123
123 % 10 = 3
So 81454-09-3 is a valid CAS Registry Number.

REDUCTIVE DEAMINATION OF ARYL- AND HETEROARYL-AMINES VIA PYRIDINIUM FLUORIDES

Katritzky, Alan R.,Chermprapai, Amornsri,Bravo, Susana,Patel, Ranjan C.

, p. 3603 - 3607 (2007/10/02)

The corresponding "pseudobase" Δ2-1,5-diketones (8) and (14) afford dihydrochromenylium (9a) and tetrahydroxanthylium monofluorides (15).These convert aryl- and heteroarylamines into dihydroquinolinium (10) and tetrahydroacridinium (16) monofluorides which at 130-250 deg C give the deaminated arenes and heteroarenes (average overall yield 60percent).
