CAS numbers without leading zeros or 7-2-1 digits

[conradspindler]

A small remark to the CAS numbers. I would remove the leading zeros, because they are not part of the CAS numbers.

This is up to you, if you want to keep them for better sorting visibility. But in case you keep the leading zeros in the CAS numbers, you need to add a zero in front everywhere, since the CAS numbers have 7-2-1 digits maximum and currently it is 6-2-1.

This is maybe also the reason why you missed some CAS numbers in your database (I only found 2 so far), for example Pydiflumetofen (1228284-64-7) or Benzovindiflupyr (1072957-71-1) because they have 7 digits in front (the maximum allowed).

Thank you, Conrad. We are aware of this.
