Check Digit Verification of cas no

The CAS Registry Mumber 220826-28-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,8,2 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 220826-28:
(8*2)+(7*2)+(6*0)+(5*8)+(4*2)+(3*6)+(2*2)+(1*8)=108
108 % 10 = 8
So 220826-28-8 is a valid CAS Registry Number.

Synthesis of aryl perfluoroalkyl sulfides from aromatic disulfides

Sipyagin,Enshov,Kashtanov,Potemkin,Thrasher,Waterfeld

, p. 420 - 434 (2007/10/03)

Thermolysis of xenon(II) bis(perfluoroalkanecarboxylates) in the presence of diaryl disulfides occurs through the S-S bond cleavage to form dihalo-, halonitro-, and halodinitrophenyl perfluoroalkyl sulfides. The latter type of compounds was obtained for the first time. The main side process is the perfluoroalkylation of the aromatic ring.
