The chemical compound "(+/-)-2-(1-carboxy-ethyl)-3-phenyl-zimtsaeure-methylester" is a chiral ester derivative of cinnamic acid, featuring a methyl ester group and a carboxyethyl side chain attached to the phenyl ring. It is a racemic mixture, meaning it contains both the R and S enantiomers. On the other hand, "β-Methyl-α-hydrogen-γ,γ-diphenyl-α-methylitaconat" is a complex organic molecule with a β-methyl group, an α-hydrogen, and two phenyl rings attached to the γ carbon of an itaconic acid derivative, which has been modified with a methyl group at the α position. (+/-)-2-<1-Carboxy-aethyl>-3-phenyl-zimtsaeure-methylester, β-Methyl-α-hydrogen-γ,γ-diphenyl-α-methylitaconat is characterized by its unique structure and potential applications in various chemical and pharmaceutical processes. Both of these chemicals are examples of the diverse range of organic compounds that can be synthesized and studied for their properties and potential uses.
The CAS Registry Mumber 1678-12-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,7 and 8 respectively; the second part has 2 digits, 1 and 2 respectively. Calculate Digit Verification of CAS Registry Number 1678-12: (6*1)+(5*6)+(4*7)+(3*8)+(2*1)+(1*2)=92 92 % 10 = 2 So 1678-12-2 is a valid CAS Registry Number.
