Chapter 2: Registration System
Overview
Registration System is a powerful, web-based
registration solution, part of the ChemOffice
Enterprise suite. The system includes a robust data
model for pure compounds, batches, salt
management, automatic duplicate checking, and
unique ID assignments.
As chemicals enter a laboratory, either via synthesis
or procurement, they need to be characterized and
tracked. Since chemical names are cumbersome,
and one compound typically has many names, the
name becomes a difficult identifier. The chemical
structure, while more exact and recognizable,
cannot be verbalized, and inclusion in written
reports is difficult. The chemical registration
number, by contrast, is a simple, compact, and
unique way of identifying a chemical substance.
Registration System
Workflow
The Registration System process begins by adding a
compound to a temporary table space in the
database. This is done using the "Add Compound"
button from the main menu. The user is taken to an
"input" screen, and the ChemDraw plug-in starts
on the client. The scientist should sketch the
molecule and fill in all known information about
that compound. If this is a new batch of an existing
compound, click the "new batch" button and enter
the existing compound's registry number. If this is
a new compound, simply sketch the molecule in the
box and complete the form.
At some time, scheduled by a person designated as
a scientific administrator, the compounds are
formally "registered". Each compound or batch is
checked against a list of existing entries for
duplication. Duplicate checking is done using an
advanced structure-matching algorithm, which
checks the molecular drawing against the database.
If no match is found, a new registry number is
assigned. If a duplicate is found, the registrar is
asked how to process the duplicate.
Chemical Registry Number
Assignment
Registry numbers are drawn sequentially from a
table. If a compound is ever removed from the
database, its registry number will not be re-used.
Starting Registration
System
When Registration System is opened, you must log
in to start working.
To open and log in to Registration System:
1. Type http://hostname into your web
browser.
The main ChemOffice WebServer window
appears.
NOTE: Hostname is the name of the ChemOffice
WebServer machine. Contact your server administrator to
obtain the correct hostname.
2. Click Registration System.
