Question

Please dont add in html script but use coding should be in javascript. It shouldnt be prompting message or alert but it should errorflag the error like the card is valid or the card is invalid when i click the purchase button.

Modulus Check Logic

 

For this project, we will be taking in 10 digit credit card numbers. Ensure the user entered only 10 numbers. If they pass this check, perform a modulus check to ensure that the user has submitted a valid credit card number.

 

Note that the checking factors below are the literal checking factors you will use in your solution.

 

Sample Credit Card Number

9434578423

Checking Factors

432765432

Multiply Checking Factors by Credit Card digits and Sum

(9 * 4) + (4 * 3) + (3 * 2) + (4 * 7) + (5 * 6) + (7 * 5) + (8 * 4) + (4 * 3) + (2 * 2) = 195

Divide the Sum by 11

195 / 11 = 17, gives a remainder of 8

Subtract

11 - 8 = 3 (this is the check digit)

Compare the check digit to the last digit in the credit card number

9434578423

The credit card number is valid when the check digit and the last digit in the credit card number are equal.

 

The following valid credit card numbers can be used for testing:

 

1111111118

2222222225

4111313135

2234321326

 

Note:

The “%” is the mathematical operator used to get the remainder.

Examples:

10 % 5 = 0, there is no remainder

10 % 3 = 1, there is a remainder of 1
