STNにおける参照文献ゼロの物質の検索
STN®データベース内に文献や特許の参照情報がないCAS REGISTRYSMの物質について詳しく調べるには、以下のフィールドを参照してください。
- 登録情報源 (SR)
CAS登録番号について®97314-93-7以降のCAS登録番号について、SRフィールドはその物質が最初に登録された理由を示しています。SRフィールドの内容は、EXPANDまたはSEARCHコマンドで検索可能です。
- クラス識別子 (CI)
CAS登録ポリシーに基づいて登録された物質については、CIフィールドからその登録理由に関する詳細な情報を得られる場合があります。

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の更新により参照文献が付与された物質
SRフィールドの内容は、物質が最初に登録された理由を示しています。ただし、REGISTRYは毎日更新されるため、当初は参照文献なしで登録された物質に、後から参照情報が追加される場合があります。以下に、他の情報源から最初に登録された物質の例を2つ挙げます。最初の例には関連する参照文献がありませんが、2番目の例にはCASM/CAS参照文献が関連付けられています。
