Check Digit Verification of cas no

The CAS Registry Mumber 253433-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,4,3 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 253433-17:
(8*2)+(7*5)+(6*3)+(5*4)+(4*3)+(3*3)+(2*1)+(1*7)=119
119 % 10 = 9
So 253433-17-9 is a valid CAS Registry Number.

Synthesis of functionalised quinolines through tandem addition/annulation reactions of β-(2-aminophenyl)-α,β-ynones

Arcadi, Antonio,Marinelli, Fabio,Rossi, Elisabetta

, p. 13233 - 13250 (1999)

β-(2-aminophenyl)-α,β-ynones can quickly give functionalized 2,4-disubstituted quinolines through tandem nucleophic addition/annulations reactions. Acid-catalysed cyclization of β-(2-aminophenyl)-α,β-ynones can also occur. The easy entry into 4-iodo-2-substituted-quinolines prompted the development of a one pot procedure for synthesis of 2,4- disubstituted quinolines by further elaboration by means of palladium-catalysed reactions. The exposure to basic conditions of one β-(2-malonylamidophenyl)-α,β-ynone led to a fused quinolone derivative through intramolecular Michael addition/tautomerisation/transesterification cascade reactions. Fused polycyclic quinolines can be viewed as occurring through a tandem concerted Diels-Alder/annulation reactions of β-(2- aminophenyl)α,β-ynones with enamines, azides and nitrile oxides.
