MS Dynamics CRM - Display Unique/Auto Number on the form before save.

My client requirement is display the unique reg number for new contact before the save record.
My Previous blog <a href="http://makdns.blogspot.com/2016/03/ms-dynamics-crm-generate-uniqueauto.html">MS Dynamics CRM - Generate Unique/Auto Number</a> will show the reg number on form after save the new contact. if the user clicks save and close, they can't see the number.

So i come up with the web service concept to generate unique number for new contact and display on the contact screen.
Also i am using SQL Server sys.sequences for generating new number.
