General Description
"(6S)-6-[5-(7-Bromo-9,9-difluoro-9H-fluoren-2-yl)-1H-imidazol-2-yl]-5-azaspiro[2.4]heptane-5-carboxylic acid phenylmethyl ester" is a complex organic compound. The name indicates its structure and molecular composition. It indicates possible aromatic rings, characterized by the presence of the fluorene and imidazole groups. It also suggests the spiro clinical feature, which typically refers to a compound with two rings sharing a single atom. The chemical also contains a carboxylic acid ester functionality, which is a common group in many naturally occurring and synthetic compounds. Bromo and difluoro denote the inclusion of bromine and fluorine atoms, suggesting halogenated nature of the compound. However, without a known context or application, it's challenging to provide more than a structural interpretation.
Check Digit Verification of cas no
The CAS Registry Mumber 1256388-49-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,3,8 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1256388-49:
(9*1)+(8*2)+(7*5)+(6*6)+(5*3)+(4*8)+(3*8)+(2*4)+(1*9)=184
184 % 10 = 4
So 1256388-49-4 is a valid CAS Registry Number.
