The chemical compound "1-Oxa-2-azaspiro[4.5]deca-2,6,8-triene-3-carboxylic acid, 7,9-dibromo-10-hydroxy-8-methoxy-, methyl ester, (5R,10S)-rel-" is a complex organic molecule with a unique structure. It features a spiro ring system, which is a type of fused ring system where two rings share a common atom. In this case, the spiro system consists of a 4.5-decatriene backbone, which is a ten-carbon chain with three double bonds. The molecule also contains a carboxylic acid group, a hydroxyl group, a methoxy group, and two bromine atoms. The stereochemistry is specified as (5R,10S)-rel, indicating the relative configuration of the chiral centers at the 5th and 10th positions. 1-Oxa-2-azaspiro[4.5]deca-2,6,8-triene-3-carboxylic acid,
7,9-dibromo-10-hydroxy-8-methoxy-, methyl ester, (5R,10S)-rel- is a derivative of a more general class of compounds known for their potential biological activities, and its specific structure suggests it may have applications in pharmaceutical or chemical research.
The CAS Registry Mumber 87580-09-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,5,8 and 0 respectively; the second part has 2 digits, 0 and 9 respectively. Calculate Digit Verification of CAS Registry Number 87580-09: (7*8)+(6*7)+(5*5)+(4*8)+(3*0)+(2*0)+(1*9)=164 164 % 10 = 4 So 87580-09-4 is a valid CAS Registry Number.
