The vinyl ester of palmitic acid is used in a variety of industrial and commercial applications, including as a chemical intermediate in the production of surfactants, lubricants, and additives for coatings and adhesives. It is also used as a raw material in the production of polymers and resins. Palmitic Acid Vinyl Ester is known for its stable chemical properties and resistance to oxidation, making it a valuable component in the manufacturing of various products.
Check Digit Verification of cas no
The CAS Registry Mumber 693-38-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 693-38:
(5*6)+(4*9)+(3*3)+(2*3)+(1*8)=89
89 % 10 = 9
So 693-38-9 is a valid CAS Registry Number.

The selective O-acylation of enolates providing a simple entry to O-enesters
Limat, Dominique,Schlosser, Manfred
, p. 5799 - 5806 (1995)
In the presence of catalytic amounts of a fluoride source, O-trimethylsilyl enethers undergo condensation with acyl fluorides to afford O-enesters with high yields. The intermediates and final products are pure (Z) isomers if only one double bond is in conjugation with the oxygen atom whereas (E) isomers prevail if silyl dienethers or trienethers and O-trienesters are formed.
