STN에서 참조 자료가 없는 물질 검색
STN® 데이터베이스에 문헌이나 특허 참조 자료가 없는 CAS REGISTRYSM 물질에 대해 자세히 알아보려면 다음 필드를 참조하십시오:
- 등록 출처(SR)
CAS 등록 번호의 경우®97314-93-7 이상인 경우, SR 필드는 해당 물질이 처음 등록된 이유를 나타냅니다. SR 필드의 내용을 EXPAND하거나 SEARCH할 수 있습니다.
- 분류 식별자(CI)
CAS 등록 정책을 지원하기 위해 등록된 물질의 경우, CI 필드를 통해 해당 물질이 등록된 이유에 대한 추가적인 정보를 확인할 수 있습니다.

A component of a multicomponent substance such as a copolymer, salt, or mixture
A ring parent, i.e., the main ring system excluding substituents
A translated protein from GenBank
|
Search the CAS Registry Number in the Component Registry Number (/CRN) field to retrieve the multicomponent substances containing this component. Many of these multicomponent substances will have references.
Display the Ring System Data information, i.e., D RSD, to obtain the Ring Identifier (RID) for the ring system, e.g., 7086.54.2. Search the first two parts of the RID in the /RID field to obtain substance(s) containing the ring system. Many of the compounds containing ring systems will have references.
Use the SEQLINK EXACT command to locate the CAS Registry Numbers for all sequences with the same backbone. Use the CAS Registry Numbers for comprehensive retrieval of associated references.

REGISTRY 업데이트로 인해 참조 자료가 생성된 물질
SR 필드의 내용은 물질이 처음 등록된 이유를 나타냅니다. 그러나 REGISTRY는 매일 업데이트되므로, 처음에는 참조 자료 없이 등록된 물질에 나중에 참조 정보가 추가될 수 있습니다. 다음은 다른 출처로부터 처음 등록된 물질의 두 가지 예입니다. 첫 번째 예는 관련 참조 자료가 없는 경우이고, 두 번째 예는 CASM/CAS 참조 자료와 연결된 경우입니다.
