The pUIMID for an ICCID is calculated from a 20 digit string.

The check digit is, however, calculated using the decimal Luhn algorithm for both 14 and 18 digit formats.

IMEI codes (14 digit codes with all decimal digits) are treated as hexadecimal numbers when the 18 digit format is calculated.

This is most useful for ICCID/LF_EUIMID because it is not always possible for the calculator to determine whether a check digit is included in non-standard ICCID numbers (19 or 20 digits).

An asterisk ('*') at the end of a digit string indicates that a check digit should be calculated.

For convenience with a test vector any input beginning with two hyphens (-) is treated as a comment and output as a header line.
