How to make a regular expression for a redirect in nginx?

Question

linux

Good day to all.
There is such a task,
it is necessary to redirect a url of the form: site.ru/page1/ru/content/ to a page of the form: newsite.com/page1/ru/#content
the following part of the nginx config successfully copes with this:
location /page1/ {
rewrite ^( .*)/(.*)/$ http://newsite.com$1/#$2 permanent;
}
but, the task also arose to process pages of the form: site.ru/page1/ru/content (that is, without "/" at the end) and redirect them to the page: newsite.com/page1/ru/#content.
The question is, can this be done with a single regular expression? If possible, please help with writing it, because I have already tried many options. If this is not possible, then how to describe these redirects within the same nginx config.

Very simple.

location /page1/ {
    rewrite ^(.+?/)(.*)/$ http://newsite.com$1#$2 permanent;
    rewrite ^(.+?/)(.*)$  http://newsite.com$1#$2 permanent;
}
