maths question about engine number

[alastair84]

Hi all, i was looking to find out the engine number for my car engine as was trying to buy the right timing belt kit for my car....
and came across a maths question lol. Just wanted to check with you brainy people my calculation.

if for example my engine number is 20AD2770....for an opel astra....1.8 sri 2002 model....

Opel/Vauxhall engines and chassis (VIN) numbers: clearing the confusion | Gates Europe

according to this article above....they say the last 6 digits are the serial number....

so if the first engine made at the plant was numbered 000001....and then they labelled the 1,000,000th engine A000001....
and then when they got to A99999, the next one was labelled B000001.....
and so on...
i calculated my engine to be the 3632770th made at the plant?

thanks in advance!

Ah yes didn't think about that....so can start with deducting 25 (26 letters of the alphabet)? then would need to take into account when it changes to AA then AB.....
