331674-50-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 331674-50-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,6,7 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 331674-50:
(8*3)+(7*3)+(6*1)+(5*6)+(4*7)+(3*4)+(2*5)+(1*0)=131
131 % 10 = 1
So 331674-50-1 is a valid CAS Registry Number.

Condensation of fluorine-substituted benzaldehydes with amines and cyclic ketones
Kozlov,Gusak
experimental part, p. 830 - 835 (2009/06/08)
Condensation of fluorine-containing benzaldehydes with naphthalen-2-amine or quinolin-6-amine and cyclic ketones (cyclopentanone, cyclohexanone, and 4-methylcyclohexanone) gave new fluorine-containing derivatives of cyclopenta[c]benzo[f]quinoline, benzo[a
