There seem to be some differences in ISIN and CUSIP validation that need to be made more clear. Let me see if I have it right:

In ISIN:

  1. The letters are converted to digits (becoming two seperate digits)
  2. The numbers are split into two groups
  3. The digits from one group (the one which contains the right most character) are multiplied by two
  4. The digits are summed
  5. etc

In CUSIP:

  1. The characters are split into two groups
  2. The digits from one group (the one which contains the right most character) are multiplied by two (letters being converted to numbers before multiplying)
  3. The digits are summed
  4. etc

So ISIN splits a letter ('C' for example) into '1' and '2' and puts them in different groups, where CUSIP groups then multplies 12 x 2


Reference: CUSIP also detailed here: http://www.cusip.com/NASApp/cusipweb/com/sp/apps/cusipaccess/html/whats.html#check

Shouldn't this sentence:

ISINs are created only for securities, and not derivatives such as options or futures.

Read:

ISINs are created only for EQUITIES, and not derivatives such as options or futures.

Since technically options and futures are securities?

See Security (finance)

Security is the legal right given to a creditor by a borrower.

In modern commerce, the creation of fungible credit, such legal interest became transformed as business people accepted the notes of third parties that were backed by credit worthy parties (banks). As a consequence a security became a type of transferable interest representing financial value. Traditionally, securities have been categorized into debt and equity securities, and between bearer and registered securities.

The uses that are made of securities have changed over time, for both the issuer and holder. Though the purpose of capital raising has sometimes been taken to be a defining characteristic of securities, its uses have expanded greatly in modern times.

They are often represented by a certificate. They include shares of corporate stock or mutual funds, bonds issued by corporations or governmental agencies, stock options or other options, limited partnership units, and various other formal "investment instruments." Banknotes, checks, and some bills of exchange do not fall into this category. Transferable interest in commodities like oil, food grains or metals can also be referred to as securities. One can enter into contracts to buy or sell various quantities of commodities in various commodity exchanges. These become transferable interest in the particular commodity.

Freely available?

The CUSIP bureau claims that anyone who uses CUSIP numbers in a database needs to pay the CUSIP bureau a licensing fee, since they say that their numbers are copyrighted.

Are ISINs free for anyone to use? Does the CUSIP bureau complain about this? —Preceding unsigned comment added by 75.146.141.142 (talk) 19:00, 11 June 2008 (UTC)[reply]
