2-Ethenylidenehexanoic acid, also known as sorbic acid, is a naturally occurring organic compound with the chemical formula C6H8O2. It is a colorless crystalline solid that is widely used as a food preservative due to its ability to inhibit the growth of mold, yeast, and bacteria. Sorbic acid is found in various fruits and berries, and it is also synthesized industrially for use in food, beverages, cosmetics, and pharmaceuticals. It is generally recognized as safe by regulatory authorities, but its use is regulated to ensure that it does not exceed specified limits to prevent potential health issues.

5665-73-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5665-73-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,6 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5665-73:
(6*5)+(5*6)+(4*6)+(3*5)+(2*7)+(1*3)=116
116 % 10 = 6
So 5665-73-6 is a valid CAS Registry Number.

The Renaissance of an Old Problem: Highly Regioselective Carboxylation of 2-Alkynyl Bromides with Carbon Dioxide

Miao, Bukeyan,Li, Gen,Ma, Shengming

supporting information, p. 17224 - 17228 (2016/01/25)

A steric effect-controlled, zinc-mediated carboxylation of different 2-alkynyl bromides under an atmospheric pressure of CO2 has been developed by careful tuning of different reaction parameters, including the metal, solvent, temperature, and additive. 2-Substituted 2,3-allenoic acids were afforded from primary 2-alkynyl bromides, whereas the carboxylation of secondary 2-alkynyl bromides yielded 3-alkynoic acids in decent yields. A rationale for the observed regioselectivity has been proposed.

Preparation of Functionally Substituted Allenes from Methylacetylenes via Propargylic Lithium Alanate or Lithium Borate Intermediates

Pearson, Norman R.,Hahn, Gregory,Zweifel, George

, p. 3364 - 3366 (2007/10/02)

Propargylic Lithium alanates or lithium borates react with allylic halides or with various carbonyl reagents in a highly regioselective manner to furnish 1,1-disubstituted allenes.
