2,4-Pentadienoic acid, 3-methyl-5-phenyl-, also known as 3-Methyl-5-phenylpentadienoic acid, is an organic compound characterized by a pentadienoic acid backbone with a methyl group at the 3rd carbon and a phenyl group at the 5th carbon. This molecule features a conjugated diene system, which is a sequence of alternating double and single bonds, and a carboxylic acid functional group. The presence of the phenyl ring introduces aromaticity and potential for various chemical reactions, such as electrophilic aromatic substitution. 2,4-Pentadienoic acid, 3-methyl-5-phenyl- is of interest in organic chemistry and may be used in the synthesis of more complex molecules or as a building block in material science.
The CAS Registry Mumber 5292-18-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,9 and 2 respectively; the second part has 2 digits, 1 and 8 respectively. Calculate Digit Verification of CAS Registry Number 5292-18: (6*5)+(5*2)+(4*9)+(3*2)+(2*1)+(1*8)=92 92 % 10 = 2 So 5292-18-2 is a valid CAS Registry Number.
