正则表达式写法

[zhujiaozi]

一个数字字符串2016370302111501;201637030211150102;2015370307111102;2016370302111501;2016370302111501
以;分割想去除前13个字符，变为501;501102;102;501正则表达式如何写？

        static void Main(string[] args)
        {
            string str = "2016370302111501;201637030211150102;2015370307111102;2016370302111501;2016370302111501";
            Console.WriteLine(Regex.Replace(str, @"\d+(\d{3})(;)?","$1$2"));//1
            Console.WriteLine(Regex.Replace(str, @"\d+(\d{3});?", "$1;").Trim(';'));//2
            Console.ReadLine();
        }

有点不对，是去除前13个数字，保留分号前面的数字（可能多余三个）。

        static void Main(string[] args)
        {
            string str = "201637030211150111111111111111;201637030211150102;20153703071112;2016370302111501;2016370302111501";
            Console.WriteLine(Regex.Replace(str, @"\d{13}(\d+)(;)?", "$1$2"));//1
            Console.WriteLine(Regex.Replace(str, @"\d{13}(\d+);?", "$1;").Trim(';'));//2
            Console.ReadLine();
        }
