Ending the support of Windows XP

Since Microsoft has ended the support for the Windows XP platform since the beginning of this year, it is now time for DOHSBASE to do likewise in DOHSBase Compare. This will allow us to make new improvements in the base program (the part that you use to look for data and make analyses).

We intend to implement the first improvements with the next update: 2015-01. This means that per January 2015 our support for Windows XP will cease.

If you expect to encounter problems with our improvement action, please contact us and we can see how we can help you find an intermediate solution. Please contact us in that case at helpdesk@dohsbase.nl

CAS-numbers amended for several substances

For a limited number of substances the same CAS-number applies to the pure substance and to the substance in an aqueous solution. The European Union has than two Index-numbers assigned to the same CAS-number. Other substances are available in different physical forms (large or small particles, for example), or with or without a “mixing component”. Also in these cases two Index-number ate assigned to the same CAS-numbers.

 

IN DOHSBase Compare the CAS-number is our unique key. To avoid problems with the uniqueness of the CAS-number we have chosen fore these situations to change the last digit of the CAS-number (a checksum) to the %-sign for the aqueous solutions, and the letter i for the substances with two physical states.

 

F.i.: the CAS-number for “Hydrogen chloride” is 7647-01-0 (with Index-number 017-002-00-2), and for “Hydrochloric acid … %” the CAS-number 7647-01-% was assigned by us (with Index-number 017-002-01-X).

 

OELV’s and measurement methods are only associated with the “original” CAS-number, without % or i in the checksum.

 

This list shows all substances with and % or i as the checksum in the CAS-number.
