cccapi

A ZeroPM R package

The goal of the cccapi package is to provide a minimal and lightweight interface to the CAS Common Chemistry API services. To get access to the API services, you need to register at https://www.cas.org/services/commonchemistry-api.

The dependencies of cccapi are kept at a bare minimum: curl for handling the API requests and jsonlite to parse data from JSON format.

Installation

You can install the development version of cccapi from GitHub with:

#| eval = FALSE
# install.packages("remotes")
remotes::install_github("ZeroPM-H2020/cccapi")

Examples

The following examples show the functionality of the three API functions of cccapi: get_detail(), get_export(), and get_search().

This is an example which shows you how to get the record details for a CAS Registry Number. In this case, for atrazine:

library(cccapi)
atz_det <- get_detail("1912-24-9")
str(atz_det)

Here is an example which shows you how to get the MOL file for a CAS Registry Number. In this case, again, for atrazine:

atz_exp <- get_export("1912-24-9")
str(atz_exp)

And finally, here is an example which shows you how to search for CAS Registry Numbers with a partial name. See ?get_search for details on the available search options!

atz_src <- get_search("atrazin*")
str(atz_src)
