194146-02-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 194146-02-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,1,4 and 6 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 194146-02:
(8*1)+(7*9)+(6*4)+(5*1)+(4*4)+(3*6)+(2*0)+(1*2)=136
136 % 10 = 6
So 194146-02-6 is a valid CAS Registry Number.

Synthesis under moderate pressure of 3-imidazo[1,2-a]pyridinylidene pyrrol-2-ones
Masurier, Nicolas,Lebrun, Aurélien,Canitrot, Damien,Chezal, Jean-Michel,Moreau, Emmanuel
, p. 2583 - 2586 (2016)
Conversion of 3-imidazo[1,2-a]pyridinylidene furan-2-ones into their pyrrol-2-one analogues was achieved efficiently with high yields, using a solution of ammonium hydroxide under moderate pressure conditions. A NMR study showed that the compounds are mainly isolated as E isomers.
