Sometimes the CIR is unable to resolve CAS numbers. This may limit the use of the RMG website if a user is unable to find the adjacency list using CAS number as a search.
Implement a screener that detects whether the user input is in the form of a CAS number, and if so, search using the CAS Common Chemistry API instead of CIR.
Issue
Sometimes the CIR is unable to resolve CAS numbers. This may limit the use of the RMG website if a user is unable to find the adjacency list using CAS number as a search.
Reproduce this
Go to the RMG molecule search (https://rmg.mit.edu/molecule_search) and search for 16940-81-1. You will see that the CIR is unable to resolve the CAS number, but if you instead search on CAS Common Chemistry (https://commonchemistry.cas.org/results?q=16940-81-1) the CAS number can be found.
Proposed fix / Todo
Implement a screener that detects whether the user input is in the form of a CAS number, and if so, search using the CAS Common Chemistry API instead of CIR.
