This regex does the job:

\(.*\)\/

Just match an opening bracket, then anything until a closing bracket with a forward slash.

Here's your regex. The part in braces will extract needed fragment

/^.+\/([^\/]+)\/.+$/

Basically, the logic is simple: ^ - marks beginning of the string

.+\/ - matches all symbols before the next part. This part of regex is composed taking into account default "greedy" behaviour of regexes, so this part matches http://farmer.gov.in/ in your example

([^\/]+) - matches all symbols between two slashes

\/.+$ - matches all symbols till the end of the string

Example with PHP language:

<?php
$string = "http://farmer.gov.in/(S(4txk2wasxh3u0slptzi20qyj))/CWC_Link.aspx";
$regex = "/^.+\/([^\/]+)\/.+$/";
preg_match($regex, $string, $matches);
var_dump($matches);
?>

In the output $matches[1] will have your needed value (S(4txk2wasxh3u0slptzi20qyj))

The key point is to notice that the () characters mark the boundaries and that no / character is in the contents:

/(\(S\([^/()]+\)\))/
