Is it possible to validate IMEI Number?

Question

For a mobile shop application, I need to validate an IMEI number. I know how to validate based on input length, but is their any other mechanism for validating the input number?

Answer 1

I think this logic is not right because this working only for the specific IMEI no - 490154203237518 not for other IMEI no ...I implement the code also...

var number = 490154203237518;
var array1 = new Array();
var array2 = new Array();
var specialno = 0 ;
var sum = 0 ;
var finalsum = 0;
var cast = number.toString(10).split('');
var finalnumber = '';
if(cast.length == 15){
    for(var i=0,n = cast.length; i
