Welcome to mod_rewrite. There's a logging facility that can create a log of
which rules were tried, but it doesn't help in this case where you only have
one rule.

You did a gread job here, but ...

1) No spaces in the [] at the end of the line, so you want [R=301,L]

2) I found I needed to add this option also:
Options +SymLinksIfOwnerMatch

3) You almost certainly also want QSA (query string append), making it
[R=301,L,QSA] at the end of the line. This will add the name parameter to
whatever other parameters were sent, instead of dropping the original
parameters:

    product-a.php?quantity=4 -> product.php?name=a&quantity=4

You can check Apache's error_log if this still isn't working for hints.
