Hello Rajendra,

Thank you so much for the post... I was wondering what is the use of MSO_PageHashCode in SharePoint

Hi

The MSO_PageHashCode is computed based off of values associated with the page.  It is used along with other checks to see if the page has been modified since it was loaded in the browser.
