No, you need to divide the MW of the CD-3 by 2 in your calculation. What developer are you trying to modify? There are other things to consider besides MW. There are two base units considered in their MW. Usually the MW of such things as CD-3 are given as the sesquisulfate.

Yes, I agree with Ian. Good choice and less toxic and less subject to aerial oxidation. However, as CD-2 comes as an acid salt, you will have to adjust the pH to the correct value. In this case I have no idea what that would mean. Maybe the Crawley formula would suggest something.
What if you tried to replace it with Paracetamol instead its sold at the local pharmacy as Tylene or Paracet I think.
I've been eyeing Sease #1 myself, a treue superfine grain develolper is good for modern-day film in oldtime cameras, to get ISO down from todays 100 - 200 ISI to yeesterdays 25 - 50 ISO, and the superfine grain is free!
