You can confirm your correct passport number by looking at the machine readable area on the bio page. On the second row, the first 9 symbols are the passport number. You should enter that in your visa application.
Similarly, your name should match what's in the machine readable area on row 1. Russian middle name ("father's name") is not what is generally considered a middle name in the Western world, so it is common that it would not show up there.
