Answer 1

Use this javascript

// multiplication table d
var d = [
    [0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
    [1, 2, 3, 4, 0, 6, 7, 8, 9, 5],
    [2, 3, 4, 0, 1, 7, 8, 9, 5, 6],
    [3, 4, 0, 1, 2, 8, 9, 5, 6, 7],
    [4, 0, 1, 2, 3, 9, 5, 6, 7, 8],
    [5, 9, 8, 7, 6, 0, 4, 3, 2, 1],
    [6, 5, 9, 8, 7, 1, 0, 4, 3, 2],
    [7, 6, 5, 9, 8, 2, 1, 0, 4, 3],
    [8, 7, 6, 5, 9, 3, 2, 1, 0, 4],
    [9, 8, 7, 6, 5, 4, 3, 2, 1, 0]
];

// permutation table p
var p = [
    [0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
    [1, 5, 7, 6, 2, 8, 3, 0, 9, 4],
    [5, 8, 0, 3, 7, 9, 6, 1, 4, 2],
    [8, 9, 1, 6, 0, 4, 3, 5, 2, 7],
    [9, 4, 5, 3, 1, 2, 6, 8, 7, 0],
    [4, 2, 8, 6, 5, 7, 3, 9, 0, 1],
    [2, 7, 9, 3, 8, 0, 6, 4, 1, 5],
    [7, 0, 4, 6, 9, 1, 3, 2, 5, 8]
];

// inverse table inv
var inv = [0, 4, 3, 2, 1, 5, 6, 7, 8, 9];

// converts string or number to an array and inverts it
function invArray(array) {

    if (Object.prototype.toString.call(array) === "[object Number]") {
        array = String(array);
    }

    if (Object.prototype.toString.call(array) === "[object String]") {
        array = array.split("").map(Number);
    }

    return array.reverse();

}

// generates checksum
function generate(array) {

    var c = 0;
    var invertedArray = invArray(array);

    for (var i = 0; i < invertedArray.length; i++) {
        c = d[c][p[((i + 1) % 8)][invertedArray[i]]];
    }

    return inv[c];
}

// validates checksum
function validate(array) {

    var c = 0;
    var invertedArray = invArray(array);

    for (var i = 0; i < invertedArray.length; i++) {
        c = d[c][p[(i % 8)][invertedArray[i]]];
    }

    return (c === 0);
}

 $(document).ready(function () {
  $('#UserForm').formValidation({
                    message: 'This value is not valid',
                    feedbackIcons: {
                        valid: 'glyphicon glyphicon-ok',
                        invalid: 'glyphicon glyphicon-remove',
                        validating: 'glyphicon glyphicon-refresh'
                    },
                    fields: {aadhaar_no: {
                            validators: {
                                digits: {
                                    message: 'Please use numeric characters only.'
                                },
                                stringLength: {
                                    min: 12,
                                    max: 12,
                                    message: 'The aadhaar number must be 12 characters long'
                                }, identical: {
                                    field: 'c_aadhaar_number',
                                    message: 'The aadhaar number and its confirm field are not the same'
                                }, callback: {
                                    message: 'The input string is not a valid Aadhaar number.',
                                    callback: function (value, validator, $field) {
                                        return validate(value);
                                    }
                                }
                            }
                        }
 });
            });

                                        Aadhaar Number *
