Introducing CheckCAS: A Free, Open-Source Tool for Validating Chemical Abstract Service Registry Numbers
If you work in the field of chemistry or related sciences, you are likely familiar with the Chemical Abstract Service (CAS) Registry Numbers. These unique identifiers are used to catalog and identify chemical substances, and they are essential for researchers, scientists, and professionals in the field to effectively collaborate and share information. However, ensuring that these registry numbers are formatted correctly and contain valid check digits can be a time-consuming and error-prone task. That’s where CheckCAS comes in.
CheckCAS is a free, open-source command-line application that validates both the format of the given registry numbers and their check digits. The tool takes a CAS number as a single argument, or a series of CAS numbers (one per line) from the standard input, and it returns valid CAS numbers in the standard output and records invalid CAS numbers in the standard error. With no arguments, CheckCAS reads from the standard input, making it easy to use the tool with other applications or text files.
Here are some key features of CheckCAS:
* Validates both the format of the given registry numbers and their check digits
* Supports a single CAS number as an argument, or a series of CAS numbers from the standard input
* Returns valid CAS numbers in the standard output and records invalid CAS numbers in the standard error
* Works on Windows, Linux, and macOS operating systems
CheckCAS is available for free download as a 6K ZIP file, and it can be used in a variety of ways to ensure that your CAS registry numbers are accurate and valid. For example, you can use CheckCAS to:
* Validate a single CAS number or a series of CAS numbers from a text file or other application
* Print valid CAS numbers to the standard output for further processing or analysis
* Record invalid CAS numbers in the standard error for review and correction
* Use the tool with other applications or scripts to automate validation and verification processes
In addition to its core functionality, CheckCAS also includes several optional arguments that allow you to customize the tool to meet your specific needs. For example, you can use the –help argument to display brief usage information and the version number of the application, or you can use the -v argument to increase the verbosity of the tool’s output.
If you are looking for a reliable and efficient tool to validate Chemical Abstract Service Registry Numbers, Look no further than CheckCAS. With its ability to validate both the format and check digits of CAS numbers, this open-source tool is an essential resource for anyone working in the field of chemistry or related sciences.
