With regard to TV channel O2TV text, this looks like a standard CV that Kashin  possibly wrote himself and provided in the place of his employment. At least, it is completely unclear who wrote this text: no name, no date, no self-explaining title. If it was a newspaper article published by someone else with name and telling that Kashin is great, that would qualify. If he published a book, one should include this book in the article. So far, I do not see any proofs of his notability in this article.
