69147-97-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69147-97-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,1,4 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 69147-97:
(7*6)+(6*9)+(5*1)+(4*4)+(3*7)+(2*9)+(1*7)=163
163 % 10 = 3
So 69147-97-3 is a valid CAS Registry Number.

SYNTHESIS OF 1H-IMIDAZOQUINOLIN-4(5H)-ONE VIA PALLADIUM-CATALYZED CYCLIZATION OF N-(2-BROMOPHENYL)-1H-IMIDAZOLE-4-CARBOXAMIDE
Kuroda, Takeshi,Suzuki, Fumio
, p. 6915 - 6918 (1991)
A new heterocycle, 5-butyl-1-methyl-1H-imidazolequinolin-4(5H)-one has been synthesized using palladium-catalyzed cyclization.A yield of the cyclization was optimized by changing base, additive and reaction temperature.
