ช่วยด้วยค่า ขอโคดตรวจสอบรูปแบบหมายเลขบัตรประชาชนหน่อยค่ะ

<script language="javascript">
function CheckID(val, args) {
if (args.Value.length == 13) {
sum = 0;
for (i = 0; i < 12; i++)
sum = sum + (args.Value.charAt(i) * (13 - i));
args.IsValid = (((11 - (sum % 11)) % 10) == args.Value.charAt(12))
}
else
args.IsValid = false;
}
</script>

Private Function VerifyCitizenID(citizenID As String) As Boolean
	'ตรวจสอบว่าทุก ๆ ตัวอักษรเป็นตัวเลข
	If citizenID.ToCharArray().All(Function(c) Char.IsNumber(c)) = False Then
		Return False
	End If

	'ตรวจสอบว่าข้อมูลมีทั้งหมด 13 ตัวอักษร
	If citizenID.Trim().Length <> 13 Then
		Return False
	End If

	Dim sumValue As Integer = 0

	For i As Integer = 0 To citizenID.Length - 2
		sumValue += Integer.Parse(citizenID(i).ToString()) * (13 - i)
	Next

	Dim v As Integer = 11 - (sumValue Mod 11)

	Return citizenID(12).ToString() = v.ToString()
End Function
