Unfortunately (or maybe fortunately), num_s_num is a special case to
indicate float numbers. For example, 1s2 is 100.0, 1s3 is 1000.0, etc.
When you try to create a symbol '912828S7912810RS, it's recogized as a
very large number which is out of range.

I think this could be a bug in Guile. It's failed to read the symbol
literal. The same code works in racket and chezscheme.
