URL re-write syntax

I have a URL: "http://www.lootza.com/Model/Public/BuyNow/buynow.php?str=NDA="

I want to re-write this url as below:

"http://www.lootza.com/buynow/NDA="

I tried to do this by writing this below code in .htaccess but not getting any luck.

RewriteEngine on RewriteRule ^$ /Model/Public/Home/ RewriteRule ^buynow/([0-9]开发者_如何学编程+)/?$ Model/Public/BuyNow/buynow.php?str=$1

Please give me write syntax.

Regards

That seems correct assuming NDA= is an numeric string.
