I want to do some client side validation using javascript in ASP.NET page.
I tried using
<script src="../../../JS/Registration.js" language="javascript" type="text/javascript" />
but its not working. Please help.

If your page is deeply pathed or might move around and your JS script is at "~/JS/Registration.js" of your web folder, you can try the following:
<script src='<%=ResolveClientUrl("~/JS/Registration.js") %>'
type="text/javascript"></script>
Comments
add like
<head runat="server">
<script src="Registration.js" type="text/javascript"></script>
</head>
OR can add in code behind.
Page.ClientScript.RegisterClientScriptInclude("Registration", ResolveUrl("~/js/Registration.js"));

Probably the file is not in the path specified. '../../../' will move 3 step up to the directory in which the page is located and look for the js file in a folder named JS.
Also the language attribute is Deprecated.
See Scripts:
18.2.1 The SCRIPT element
Deprecated. This attribute specifies the scripting language of the contents of this element. Its value is an identifier for the language, but since these identifiers are not standard, this attribute has been deprecated in favor of type.
Edit
Try changing
<script src="../../../JS/Registration.js" language="javascript" type="text/javascript" />
to
<script src="../../../JS/Registration.js" language="javascript" type="text/javascript"></script>

I am sure, file is present at this path.

Maybe you're using master pages or something else and not quite sure where the files are launched. Simply open the file in the browser, press "view source" and use the JS path in the URL to see if it opens. Your syntax is (more or less) correct.

type="text/javascript" is also not necessary hereI assume that you are using MasterPage so within your master page you should have
<head runat="server">
<asp:ContentPlaceHolder ID="head" runat="server">
</asp:ContentPlaceHolder>
</head>
And within any of your pages based on that MasterPage add this
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
<script src="js/yourscript.js" type="text/javascript"></script>
</asp:Content>

Great answer if you are using master pages.
ScriptManager control can also be used to reference javascript files. One catch is that the ScriptManager control needs to be place inside the form tag. I myself prefer ScriptManager control and generally place it just above the closing form tag.
<asp:ScriptManager ID="sm" runat="server">
<Scripts>
<asp:ScriptReference Path="~/Scripts/yourscript.min.js" />
</Scripts>
</asp:ScriptManager>
<script>tags aren't self closing. You should be using</script>.
