Check Digit Verification of cas no
The CAS Registry Mumber 28361-43-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,3,6 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 28361-43:
(7*2)+(6*8)+(5*3)+(4*6)+(3*1)+(2*4)+(1*3)=115
115 % 10 = 5
So 28361-43-5 is a valid CAS Registry Number.

supporting information, p. 15037 - 15040 (2014/12/11)
An unprecedented double C-S bond formation method has been developed to prepare both symmetric and unsymmetric diarylsulfones with simple arenes in a single step. This represents the first example that K2S2O8 can be employed as a highly effective sulfonating agent to synthesize diarylsulfones. The reaction demonstrates excellent reactivity, good functional group tolerance and high yields.
