+This file contains more detailed doctests for the stdnum.ru.ogrn module.
+
+These tests validate the format, normalization, and validity of various
+OGRN numbers, ensuring they conform to expected behavior.
+
+>>> from stdnum.ru import ogrn
+>>> from stdnum.exceptions import *
+
+This is a list of OGRNs that should all be valid numbers:
+
+>>> valid_numbers = [
+... "1027739552642", "1137847171846", "1159102022738",
+... "1022600000092", "1022500001930", "1022500001061",
+... "1022500000566", "1022700000685", "1022500001325",
+... "1027100000311", "1022500000786", "1024100000121",
+... "1022400007508", "1022400000160", "1022400010005",
+... "1022300001811", "1020500003919", "1022300003703",
+... "1022300000502", "1022200531484", "1022200525819"
+... ]
+>>> all(ogrn.is_valid(x) for x in valid_numbers)
+True
+
+These are some numbers that should be invalid:
+
+>>> invalid_numbers = [
+... "1027739552", "", "1027739",
+... "11677", "315774600002662123"
+... ]
+>>> all(not ogrn.is_valid(x) for x in invalid_numbers)
+True
+
+Testing normalization of OGRN strings:
+
+>>> ogrn.normalize("1027739552642")
+'1027739552642'
+>>> ogrn.normalize("OGRN 1027739552642")
+'1027739552642'
+>>> ogrn.normalize("102773955")
+>>> ogrn.normalize("10277395587984375943")
+
+Ensure OGRN can be formatted as expected:
+
+>>> ogrn.format("1027739552642")
+'1027739552642'
