10-(bromoacetyl)-9-fluoro-2,3-dihydro-3-methyl-7-oxo-7H-pyrido[1,2,3-de][1,4]benzoxazine-6-carboxylic acid is a complex organic compound with a molecular formula of C16H12BrFNO5. It is characterized by a pyrido[1,2,3-de][1,4]benzoxazine core structure, which is a fused ring system consisting of a pyridine and a benzoxazine. The molecule features a 9-fluoro substitution, indicating the presence of a fluorine atom at the 9th position, and a 3-methyl group, which is attached to the 3rd carbon of the dihydro ring. Additionally, it has a bromoacetyl group at the 10th position, which is an acetyl group (a two-carbon chain ending in a carbonyl group) with a bromine atom attached to the carbonyl carbon. The molecule also contains a 7-oxo group, indicating a carbonyl group at the 7th position, and a 6-carboxylic acid functional group, which is a carboxylic acid group attached to the 6th carbon. 10-(bromoacetyl)-9-fluoro-2,3-dihydro-3-methyl-7-oxo-7H-pyrido<1,2,3-de><1,4>benzoxazine-6-carboxylic acid is likely to be used in the synthesis of pharmaceuticals or other organic compounds due to its unique structure and functional groups.

Check Digit Verification of cas no

The CAS Registry Mumber 91188-96-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,1,8 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 91188-96:
(7*9)+(6*1)+(5*1)+(4*8)+(3*8)+(2*9)+(1*6)=154
154 % 10 = 4
So 91188-96-4 is a valid CAS Registry Number.
