cusip

An CUSIP type for working with validated Committee on Uniform Security Identification Procedures (CUSIP) identifiers as defined in ANSI X9.6-2020. There is also a companion type CINS for working with the subset of CUSIP identifiers that conform to the CINS standard.

This crate is part of the Financial Identifiers series:

• CIK: Central Index Key (SEC EDGAR)
• CUSIP: Committee on Uniform Security Identification Procedures (ANSI X9.6-2020)
• ISIN: International Securities Identification Number (ISO 6166:2021)
• LEI: Legal Entity Identifier (ISO 17442:2020)

Usage

Add this to your Cargo.toml:

[dependencies]
cusip = "0.3.1"

Example

use cusip;
let cusip_string = "023135106"; // Amazon.com Inc - Common Stock
match cusip::parse(cusip_string) {
    Ok(cusip) => {
        println!("Parsed CUSIP: {}", cusip.to_string()); // "023135106"
        println!("  Issuer number: {}", cusip.issuer_num()); // "023135"
        println!("  Issue number: {}", cusip.issue_num()); // "10"
        println!("  Check digit: {}", cusip.check_digit()); // '6'
    }
    Err(err) => panic!("Unable to parse CUSIP {}: {}", cusip_string, err),
}
