22502-49-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 22502-49-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,5,0 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 22502-49:
(7*2)+(6*2)+(5*5)+(4*0)+(3*2)+(2*4)+(1*9)=74
74 % 10 = 4
So 22502-49-4 is a valid CAS Registry Number.

Multistep Reversible Redox Systems. 48. 1,3-Bisquinone Methide Cyclobutanes and Related Bicyclobutanes: Syntheses and Redox Properties
Freund, Wolfgang,Huenig, Siegfried
, p. 2154 - 2161 (2007/10/02)
A new approach to quinone methides is presented, which starts from diazides and thioketones.Together with some model compounds, 1,3-bisquinone methide cyclobutanes 23, 25, and 37 were synthesized.Reduction with sodium transforms these quinoid compounds in
