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.

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.

Paragraph 0044-0045, (2017/05/15)
The invention relates to a method for separating a mixture containing at least one carboxylic acid vinyl ester of general formula R′—C(O)O—CH═CH2 and at least one carboxylic acid of general formula R′—COOH, wherein R′ in either case can be an aliphatic group having 12 to 22 C atoms or a cycloaliphatic group having 12 to 22 C atoms, or an aromatic group having 12 to 22 C atoms, and R′ can be identical or different, characterized in that the carboxylic acid is converted to its anhydride R′—C(O)—O—C(O)—R′ and the carboxylic acid vinyl ester is subsequently separated.
