6608-20-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6608-20-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,0 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6608-20:
(6*6)+(5*6)+(4*0)+(3*8)+(2*2)+(1*0)=94
94 % 10 = 4
So 6608-20-4 is a valid CAS Registry Number.

Synthesis of flavone-3-sulfonylureas
Loewe, Werner,Matzanke, Norbert
, p. 943 - 948 (2007/10/03)
The synthesis of new flavone-3-sulfonylurea derivatives is hereby described. The influence of a phenyl group in the 2-position and an acetate group in the 8-position at the chromone nucleus on the activity was studied. Only weak cytostatic activity of the
