    You nonchalantly state, that a number of ... products is plural. In German singular is correct here. In English, I think I have seen both, while the plural form is more common. To me a number logically is singular, and a number of anything is still only a number. What is the difference to a flock, a pile, a cluster of anything? Would be a correct, too?

    *a in the last sentence should read: "a)" :-)

    The difference is that a flock or a pile is a collective noun, a number is not. The flock is a thing of itself. A number of sheep is not the same as a flock - the sheep could be anywhere and still be numbered, even on different farms, whereas a flock has to all be in one place. 

    "A number of sheep have fallen asleep. Three are in Germany, and two in France, while several more are in the UK," versus "A flock of sheep has fallen asleep." (-:
