106319-27-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 106319-27-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,3,1 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 106319-27:
(8*1)+(7*0)+(6*6)+(5*3)+(4*1)+(3*9)+(2*2)+(1*7)=101
101 % 10 = 1
So 106319-27-1 is a valid CAS Registry Number.

Synthesis and Structure of 2-Phenyl-4-aryl-3,4,5,6-tetrahydrobenzoquinazolines
Perjesi, Pal,Foeldesi, Andras,Tamas, Jozsef
, p. 167 - 176 (2007/10/02)
The reaction of 2-arylidene-1-tetralones 1 with benzamidine gave 2-phenyl-4-aryl-3,4,5,6-tetrahydrobenzoquinazolines 2.Investigations on the tautomeric equilibria of 2 by IR, 1H- and 13C-NMR showed the compounds to exist predominantly in the tautomeric
