(KOSDAQ: 191410) — research page\n\nAs of 2026-11-06 · kr-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is RYUK-IL C&S., Ltd., listed on KOSDAQ under ticker 191410, ISIN KR7191410000. Its LEI is not on the record, as no GLEIF record is registered under 109-86-07323.

The chapter's orderability section carries no client categories, so the outcome cannot name its client category. The rule version is acm-68000/kr/suitability-and-appropriateness-fscma-articles-46-and-46-2/r1, and the chapter as-of date is 2026-11-04.\n\n## Coverage\n\nThe record holds no research houses named on the issuer's investor-relations page, as none was found on the pages read.\n\n## Open research\n\nThe record holds no openly published research notes for this issuer, as none was found.\n\n## Licensed\n\nLicensed research: none loaded.

The live record began on 2026-09-12. Years 2021 through 2026 are sealed in the store but are not served as of a date, and the as-of door answers not_sealed.\n\n## Sources\n\n8 source pages are named on this page; every value above carries its own source page and read date in the numbers.\n\n- https://kind.krx.co.kr/corpgeneral/corpList.do?method=download&searchType=13 (identity.exchange)\n- https://data.krx.co.kr/comm/bldAttendant/getJsonData.cmd (identity.isin)\n- https://opendart.fss.or.kr/api/company.json?corp_code=00843900 (identity.jurisdiction)\n- https://mcp.kr-cm-kg.ai/events/KOSDAQ/191410 (the disclosure lines)\n- https://kind.krx.co.kr/investwarn/tradinghaltissue.do?method=searchTradingHaltIssueMain (the halt flag)\n- https://dart.fss.or.kr/dsaf001/main.do?rcpNo=20260319000768 (the auditor)\n- https://mcp.kr-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://mcp.kr-cm-kg.ai/record/KOSDAQ/191410 (the record)\n",
