Final answer:
The references provided are ISBNs for books and not NSNs. NSNs are 13-digit numeric codes used in the NATO supply system and would appear on an actual MSDS/SDS, not within book numbers. To find the NSN, one should refer to the MSDS/SDS of the product.
Step-by-step explanation:
The question pertains to identifying the National Stock Number (NSN) of an item using the information provided on a Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS). However, the references you've provided appear to be a set of ISBNs for books, not NSNs for items.
NSNs are 13-digit codes used to identify standardized material items of supply within the NATO (North Atlantic Treaty Organization) coding system, and they are not interchangeable with ISBNs, which are used for books. The ISBNs and codes you've supplied seem to relate to various publications or editions of books, probably used within a particular field or industry.
To find the NSN of a particular item, one would typically refer to the actual MSDS/SDS associated with that product. The MSDS/SDS would include crucial information about the chemical product, such as its composition, hazards, handling and storage procedures, and first-aid measures.
The NSN would likely be listed in the product identification section of the MSDS/SDS. If you are in possession of the actual MSDS/SDS document, you should look for a 13-digit numeric code, often labeled directly as "National Stock Number (NSN)" or sometimes as "NIIN" (National Item Identification Number) which forms the last 9 digits of the NSN.
