Passive ......

.
Yes.

Management requires customers to check...

How about if i change the sentence to "Active" like below:- is correct?

The amount and examine all notes in exchange are requiring Customers to check before leaving counter

.
No-- you made a big mess of it. Your choices:

Customers are required to check...
Management requires customers to check...

okie, thanks :-)

Management requires customers to check the amount and examine all nows in exchange before leaving counter

What is wrong with "Customers are required to check..."

If you want to have it in active form, consider the following:

Checking of the amount and examination of all notes in exchange before leaving counter is requirted.

or,

It is requirted that customers should check the amount and examine all notes in exchange before leaving counter.

Thanks:)

It is nothing wrong with "Customers are required to check...", i just want to change the sentence to Active Form. Your answer is useful, thks

Sorry, your example is Passive Form right?

1-Checking of the amount and examination of all notes in exchange before leaving counter is requirted.

2-It is requirted that customers should check the amount and examine all notes in exchange before leaving counter.

Sorry, that's passive. Here MM is correct. You need to supply a subject to convert your sentence to active form.

Okie, thks anyway.
