10,12-Dimethyl-2-oxo-3-phenyl-2H,6H-1,11-dioxa-4,6-diaza-naphthacene-5,7-dicarboxylic acid bis-diethylamide is a complex organic compound with the molecular formula C27H29NO6. It is characterized by a naphthacene core, which is a fused ring system similar to naphthalene but with an additional ring. The molecule features two methyl groups at the 10 and 12 positions, a phenyl group at the 3 position, and two carboxylic acid groups at the 5 and 7 positions. These carboxylic acids are each amide-linked to diethylamine, forming bis-diethylamide. 10,12-Dimethyl-2-oxo-3-phenyl-2H,6H-1,11-dioxa-4,6-diaza-naphthacene-5,7-dicarboxylic acid bis-diethylamide is known for its potential applications in pharmaceuticals and as a chemical intermediate due to its unique structure and functional groups.
The CAS Registry Mumber 87039-89-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,0,3 and 9 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 87039-89: (7*8)+(6*7)+(5*0)+(4*3)+(3*9)+(2*8)+(1*9)=162 162 % 10 = 2 So 87039-89-2 is a valid CAS Registry Number.
