Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 100,725 and was likely granted around 1870.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 100725 first appears in π at position 369,067 of the decimal expansion (the 369,067ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
