Off topic:Filter Out Only Ccds (Consenses Cds) Sequences From List Of Ensembl Transcripts

Question

[hicsuntdrac0nis]

I have a list of mouse Ensembl gene IDs in the form of:

ENSMUSG00000022973

I input them into http://biodbnet.abcc.ncifcrf.gov/ to extract all of the transcript IDs that correlate with the gene IDs to get:

ENSMUST00000118246
ENSMUST00000170853
ENSMUST00000129743
ENSMUST00000129041
ENSMUST00000121759
ENSMUST00000130813
ENSMUST00000154276
ENSMUST00000125032
ENSMUST00000156140
ENSMUST00000118390

Only two of these have a CCDS, namely:

ENSMUST00000121759
ENSMUST00000170853

How can I filter these out for ALL of the transcripts associated with ALL of the gene IDs?
