110523-75-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 110523-75-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,5,2 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 110523-75:
(8*1)+(7*1)+(6*0)+(5*5)+(4*2)+(3*3)+(2*7)+(1*5)=76
76 % 10 = 6
So 110523-75-6 is a valid CAS Registry Number.

A New Route to 6-Azachromones. An Improved Synthesis of 2-Azaxanthone
Cordonnier, Guy,Sliwa, Henri
, p. 111 - 115 (2007/10/02)
Condensation of the morpholine enamine of 1-benzyl-4-piperidone with β-ketoesters yielded 6-azatetrahydrochromones which were debenzylated and aromatized to 6-azachromones; 2-azaxanthone has been thus obtained with an improved yield as compared to previous syntheses.
