Identifying memory for a laptop

I have to do a memory upgrade for someone else's laptop.

When I visit I want to be sure I have the right type on me and doing a remote Crucial memory check on the system I see it requires the following.

I also happen to have a spare 512mb memory module from another laptop but I am not sure if it is the same.

It says on the chip the following information:
"
V916764b24qbfw
512mb 2rx16 ddr2-667mhz cl5
Pc2-5300s-555-12-a1
0703-s2655507
"

Can anyone confirm to me if the following will work as that given on the link above?

Don't want to buy memory unnecessary but at the same time I don't want to visit and then find the memory I have does not work.

Many thanks
