CAAT and P/A

hello Sir,
I just want to confirm whether following audit tests (audit software) for Payables using Caat are correct ?
1.Cast the payable ledger and agree to payable ledger account to confirm completness and accuracy of Payables in payable ledger and payable control account
2.Performance of aged payable analysis to identify any old liabilities.
3.selecting a reprentative sample of Payables for circularisation/supplier statement reconciliation as it is more objective and appropriate approach for selecting a sample
4.cast the list of payables to ensure it adds up thus confirming the arithmetical accuracy
5.perform ratio calcultion for analytical procedures on purchases and payables.
