CDS mean Sequence coding for amino acids in protein (includes stop codon)

For example,

Key             Location/Qualifiers
CDS             23..400
                /product="alcohol dehydrogenase" 
                /gene="adhI"

might be read as:

The feature  CDS  is a coding sequence beginning at base 23 and ending at base 400, has a product called 'alcohol dehydrogenase' and corresponds to the gene called 'adhI'.

A more complex description:
 

Key             Location/Qualifiers
CDS             join(544..589,688..1032)
                /product="T-cell receptor beta-chain"
                /partial

which might be read as:

This feature, which is a partial coding sequence is formed by joining the indicated elements to form one contigous sequence encoding a product called T-cell receptor beta-chain.
