i answered a little bit untrue (only a little bit), because
also for D it is possible - but not only by comparing the "official caseback-number" for a D-series with another number from
D-series, from wich you know both numbers. Than you can find out by mathematics.
complicaded ?
Yes really
But don´t worry - the 5402 you show us is no D-Series, if number 99XXX is correct.
