FIND MISSING SAFETY DATA SHEET (SDS)

This program is designed to find and download safety data sheet of chemical using CAS number.


CONTENTS

DETAILS

  • Provided with a list of CAS numbers, this program searches and downloads safety data sheet (SDS) into a designated folder. If a download folder is not provided, SDS will be downloaded into folder 'SDS' inside folder find_sds.
  • This program uses multithreading to speed up the download process. By default, ten threads are used but it can be changed depends on running computer.
  • Downloaded SDS are saved as '<CAS_Number>-SDS.pdf'
  • Lookup databases include:

REQUIREMENTS


USAGE

  1. Clone this repository:

    $ git clone https://github.com/khoivan88/find_sds.git    #if you have git
    # if you don't have git, you can download the zip file then unzip
  2. Change into the directory of the program:

    $ cd find_sds
  3. (Optional): create virtual environment for python to install dependency: Note: you can change find_sds_venv to another name if desired.

    $ python -m venv find_sds_venv   # Create virtual environment
    $ source find_sds_venv/bin/activate    # Activate the virtual environment on Linux
    # find_sds_venv\Scripts\activate    # Activate the virtual environment on Windows
  4. Install python dependencies:

    $ pip install -r requirements.txt
  5. Example usage:

    $ python
    >>> from find_sds.find_sds import find_sds
    >>> cas_list = ['141-78-6', '110-82-7', '67-63-0', '75-09-2', '109-89-7',
    ...     '872-50-4', '68-12-2', '96-47-9', '111-66-0', '110-54-3',
    ...     '00000-00-0',    # invalid CAS number, or unknown CAS
    ... ]
    >>> download_path = 'SDS'
    >>> find_sds(cas_list=cas_list, download_path=download_path, pool_size=10)
    Downloading missing SDS files. Please wait!

    Summary:
            1 SDS files are missing.
            10 SDS files downloaded.
    
    
    (Optional): you can turn on debug mode (more error printing during search) using the following command:
    python find_sds/find_sds.py  --debug
