121673-65-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121673-65-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,6,7 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 121673-65:
(8*1)+(7*2)+(6*1)+(5*6)+(4*7)+(3*3)+(2*6)+(1*5)=112
112 % 10 = 2
So 121673-65-2 is a valid CAS Registry Number.

A REGIOSELECTIVE SYNTHESIS OF 2-ALKYLFUROQUINOLIN -4(5H)-ONES
Majumdar, Krishna C.,Choudhury, Prabir K.
, p. 73 - 78 (2007/10/02)
The title compounds (2a-h) were obtained in moderate yields by simply refluxing 1-alkyl-4-hydroxyquinolin-2(1H)-ones (1a,b) with a number of acetylenic halides in n-butanol in the presence of anhydrous potassium carbonate.Compounds (2h,i) were also obtain
