Is robot.txt correct?

Question

robots.txt

Have I configured robot.txt correctly?
I have a product page that is available at site.ru/product/product_id (there are many). Will my products be displayed in the search engine when I add the site to webmaster.yandex.ru ?

User-agent: YandexBot,Googlebot
Crawl-delay: 1
Host: http://site.ru
Disallow: /ordergo
Disallow: /admin
Disallow: /login
Disallow: /register

Here is an example:
There is a page with a product, this page has the title "Computer SDL-500", and the description "buy Computer SDL-500" - (the page is available at site.ru/product/5).
Will the page be displayed in a search engine if I type for example: buy Computer SDL-500 inexpensively.
