JavaScript

if ( str.length != 11) 
  return false;

var l = str.match(/[A-Za-z]/g);
var p = str.match(/[0-9]/g);

if ( l.length != 10 || p.length != 1)
   return false;
return true;

  else
   {
var numcount=0;
var alphabetcount=0;
    for (n = 0; n < num.length; n++)
     {
      if( num.charCodeAt(n) >= 48 && num.charCodeAt(n) <= 57)
       {numcount=numcount+1; }
      else if((num.charCodeAt(n)>=65 && num.charCodeAt(n) <= 92) ||(num.charCodeAt(n)>=97 && num.charCodeAt(n) <= 122))
