5719-23-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5719-23-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,1 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5719-23:
(6*5)+(5*7)+(4*1)+(3*9)+(2*2)+(1*3)=103
103 % 10 = 3
So 5719-23-3 is a valid CAS Registry Number.

Generation and trapping of 5,6-dimethylenepyrimidin-4-ones in Diels-Alder and Michael additions

Tome, Augusto C.,Cavaleiro, Jose A. S.,Storr, Richard C.

, p. 1723 - 1734 (2007/10/03)

Pyrimidone fused sulfones 5-7 were obtained from the reaction of amidines with 3-methoxycarbonyl-4-oxotetrahydrothiophene followed by N-methylation and oxidation with mCPBA. On heating in solution at 150°C, extrusion of SO2 occurred to give the highly reactive 5,6-dimethylenepyrimidin-4-ones which were intercepted in situ in Diels-Alder reactions to give the adducts 24-28 and in conjugate addition reactions with thiol nucleophiles to give the thioethers 29 and 30.
