Hi Chandar,

Yes you can call the Apex class from Wrokflow using Outbound message.  please follow the steps.

Step 1 : Create the Site in Setup --> App Setup --> Develop --> Sites
Step 2 : Create the REST based class using @RestResource(urlMapping='/<<Name>>/*')
Step 3 : Provide the class access for the Site created above and provide the objects and class permission for the profile.
Step 4 : Copy the URL of the Site including urlmapping of the class.
Step 5 : Create Outbound message past the URL
Step 6 : Activate the Workflow 
// URL for Outbound message
// => http://DomainName/SiteName/services/apexrest/<urlMappingName>/notification

@RestResource(urlMapping='/<Name>/*')
global with sharing class ClassName{

   @HttpPost
    global static void methodName()
    {
     // do your logic
   }

}

Testing : 
https://workbench.developerforce.com/restExplorer.php

place the URL from
/services/apexrest/<urlMappingName>/notification 
the Execute it.

Thanks

You can use process builder here instead of using workflow. Process builder provides you an option to call your apex code directly
