920490-93-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 920490-93-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,0,4,9 and 0 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 920490-93:
(8*9)+(7*2)+(6*0)+(5*4)+(4*9)+(3*0)+(2*9)+(1*3)=163
163 % 10 = 3
So 920490-93-3 is a valid CAS Registry Number.

Et3N-induced demethylation-annulation of 3-alkynyl-4-methoxy-2- pyridones and structurally related compounds in the synthesis of furan-fused heterocycles

Conreaux, David,Belot, Sebastien,Desbordes, Philippe,Monteiro, Nuno,Balme, Genevieve

supporting information; scheme or table, p. 8619 - 8622 (2009/04/11)

(Chemical Equation Presented) Various 3-iodo-4-methoxypyridin-2-ones and related pyrone and coumarin derivatives have been demonstrated as readily available precursors of 2-substituted furan-fused heterocycles by means of in situ sequential Sonogashira-acetylide coupling, dealkylation, and regioselective furan annulation reactions. A Et3N-induced SN2 process has been established that accounts for the dealkylation process.
