## Retrieve Drug Molecules in InChI Format from the CAS Database

### Description

Retrieve Drug Molecules in InChI Format from the CAS Database

### Usage

    getMolFromCAS(id, parallel = 5)

### Arguments

`id` | A character vector, as the CAS drug ID.
`parallel` | An integer, the parallel parameter, indicates how many process the user would like to use for retrieving the data (using RCurl), default is `5`. For regular cases, we recommend a number less than `20`.

### Details

This function retrieves drug molecules in InChI format from the CAS database. CAS database only provides InChI data, so here we return the molecule in InChI format, users could convert them to SMILES format using Open Babel (http://openbabel.org/) or other third-party tools.

### Value

A length of `id` character vector, each element containing the corresponding drug molecule.
