Registration is broken down into three parts. 1) Email validation (You must register with your official email address). An automated email will be sent to the registrants email address with a validation link. Once the registrant clicks the link to validate ownership of the email address, the registration is sent to the Chemical Companion Team for review. 2) Review of the application is to confirm Country, Organization, and standing as a supported end user. The team may reach out to the registrant or to their organizations leadership for validation. 3) An approval or rejection email will be sent to the registrant. If approved then the registrants account is updated to issue a License and allow for software download.
