Structural Isomer
cis isomer of 1,3-dioxane-5-carboxylic acid, 2-phenyl-, trans-
Explanation
Structural isomers are compounds with the same molecular formula but different spatial arrangements of atoms. In this case, the cis isomer has the phenyl group and the carboxylic acid group on the same side of the dioxane ring, while the trans isomer has them on opposite sides.
Explanation
This compound belongs to a specific class of organic compounds, which are characterized by the presence of a dioxane ring and a carboxylic acid functional group.
Explanation
The compound contains a carboxylic acid group (-COOH), a dioxane ring (a six-membered ring with two oxygen atoms), and a phenyl group (a six-membered aromatic ring with alternating single and double carbon-carbon bonds).
Explanation
Due to its unique chemical properties, 1,3-dioxane-5-carboxylic acid, 2-phenyl-, cisis used as a starting material or intermediate in the synthesis of various pharmaceuticals and organic compounds.

Check Digit Verification of cas no
The CAS Registry Mumber 190191-51-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,1,9 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 190191-51:
(8*1)+(7*9)+(6*0)+(5*1)+(4*9)+(3*1)+(2*5)+(1*1)=126
126 % 10 = 6
So 190191-51-6 is a valid CAS Registry Number.

Conformational Analysis of 5-Substituted 1,3-Dioxanes. 7. Effect of Lithium Bromide Addition
Juaristi, Eusebio,Díaz, Francisco,Cuéllar, Geiser,Jiménez-Vázquez, Hugo A.
, p. 4029 - 4035 (2007/10/03)
The position of equilibria, established by means of BF3, between diastereomeric cis- and trans-5- substituted-2-phenyl-1,3-dioxanes, in solvents THF and CHCl3, and in the presence of 0, 1, and 10 equiv of LiBr has been determined. The observed ΔG° values show that the addition of salt to the reaction medium influences the position of equilibrium. Lithium bromide effects on the conformational behavior are discussed in terms of lithium ion complexation events that lead to increased stability of the axial isomers when the substituent at C(5) is CO2H, CO2CH3, CONHCH3, and CH2- OH. By contrast, disruption of the intramolecular hydrogen bond present in the axial 5-acetamido derivative (cis-9 substituent equal to NHCOCH3) modifies the preference for the axial conformation in salt-free 9 to a net dominance of the equatorial isomer in the presence of LiBr. Interpretation of the experimental observations was based on models that are apparently supported by semiempirical AM1 calculations. The results derived from the present study contribute to our understanding of the processes involved in molecular recognition and may model salt effects in physiological events.
