If you have a list of links and you want to check if they're live, you can use scrapebox.
you can find it here http://www.getrank.org/tools/edu-backlink-checker/
A tool such as ahrefs (google) will not only show you the authority value of each link, but a break down of your link profile.
Number of linking domains
Number of linking IPs
Seperated by .edu,.com,.org and so forth.
If you don`t have scrapebox, you can just use the free scrapebox linkchecker
Just google it !
It is faster than scrapebox normal checking
