I have a scheduled KNIME flows that processes transactionsdone on mobile devices. I need to be able to validate IMEI numbers to confirm whether they are valid. The check is done with the LUHN algorithm, where every second number is doubled, and then all the separate digits are added together.
There is a further validation step using the formula (10-(s mod10)) mod10, but this can be done in a math node.
Does anyone have KNIME solution to do this?
tC/.
I would use a Python Script node and just copy this code here (python - Implementation of Luhn Formula - Stack Overflow - hoping that this is okay) in to the node and ask K-AI to make it run
Since K-AI is available Iām a very lazy programmer
KAI is on my christmas card list
@TigerCole KI suggested two implementations. One with KNIME Expressions the other one with Python
