p-Difluor-tetraacetoxy-benzol, also known as 4,4'-(1,4-phenylenediyl)bis(2-fluoro-2-oxoacetic acid), is a chemical compound characterized by its benzene ring structure with two fluorine atoms and four acetoxy groups attached. This molecule is a derivative of benzene, where the hydrogen atoms at the para positions are replaced by fluorine atoms, and the remaining positions are occupied by acetoxy groups. It is a white crystalline solid with potential applications in various chemical synthesis processes, such as the production of pharmaceuticals and agrochemicals, due to its unique reactivity and properties.
The CAS Registry Mumber 1554-98-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,5 and 4 respectively; the second part has 2 digits, 9 and 8 respectively. Calculate Digit Verification of CAS Registry Number 1554-98: (6*1)+(5*5)+(4*5)+(3*4)+(2*9)+(1*8)=89 89 % 10 = 9 So 1554-98-9 is a valid CAS Registry Number.
