Check Digit Verification of cas no

The CAS Registry Mumber 420111-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,0,1,1 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 420111-89:
(8*4)+(7*2)+(6*0)+(5*1)+(4*1)+(3*1)+(2*8)+(1*9)=83
83 % 10 = 3
So 420111-89-3 is a valid CAS Registry Number.

Synthesis of aryl perfluoroalkyl sulfides from aromatic disulfides

Sipyagin,Enshov,Kashtanov,Potemkin,Thrasher,Waterfeld

, p. 420 - 434 (2004)

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.

Preparation of the first ortho-substituted pentafluorosulfanylbenzenes

Sipyagin, Alexey M.,Bateman, Colin P.,Tan, Ying-Teck,Thrasher, Joseph S.

, p. 287 - 295 (2007/10/03)

The preparation of the first ortho-substituted pentafluorosulfanylbenzenes was achieved. Oxidative fluorination (AgF2) of a series of aromatic disulfides containing different substituents ortho to the disulfide moiety gave only one ortho-substi
