C# string starts with a number regex

I've been searching around for a little while to figure out how to confirm a string begins with a number. I came across a regex statement '/^\d/' which I can confirm says if starts with digit. However I can not seem to get it to work in the code below. Where did I went wrong in the statement if(Regex.Match(info,"/^\d/"))?

//String attachbody is the attachment body from an email C read into a string
string[] data = Regex.Split(attachbody, "\n");

foreach (String info in data)
{
    if (Regex.Match(info,"/^\d/"))
    {
        string[] tabbedHeaderData = Regex.Split(info, "\t");
        TicketID = tabbedHeaderData[0].ToString();
        Status = tabbedHeaderData[1].ToString();
        URL = tabbedHeaderData[2].ToString();
        InitCats = tabbedHeaderData[3].ToString();
        PostRevCats = tabbedHeaderData[4].ToString();
        ListNumClosed = tabbedHeaderData[5].ToString();

        Console.WriteLine(TicketID);
        Console.WriteLine(Status);
        Console.WriteLine(URL);
        Console.WriteLine(InitCats);
        Console.WriteLine(PostRevCats);
        Console.WriteLine(ListNumClosed);
        Console.ReadLine();
    }
}

example data (tab delimited):
