Dear Student
 
The name of this compound is HCO-O-COCH3 ethanoic methanoic anhydride. (not acid)
This is an example of mixed anhydride. This anhydride is formed from methanoic acid and ethanoic acid.
CH3CH2NHCH3  is N-methylethanamine.
This is the first rule for naming organic compounds according to IUPAC, which suggests always select the longest continuous chain of carbons.
 
We hope that clarifies your query.
