Check Digit Verification of cas no

The CAS Registry Mumber 557099-37-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,7,0,9 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 557099-37:
(8*5)+(7*5)+(6*7)+(5*0)+(4*9)+(3*9)+(2*3)+(1*7)=193
193 % 10 = 3
So 557099-37-3 is a valid CAS Registry Number.

1-Chloro-2,6-dinitro-4-perfluoroalkylthiobenzenes in the synthesis of heterocycles

Sipyagin,Enshov,Kashtanov,Thrasher

, p. 1375 - 1381 (2002)

1-Chloro-2,6-dinitro-4-perfluoroalkylthiobenzenes was obtained in first time by perfluoroalkylation of bis(4-chloro-3,5-dinitrophenyl)disulfide in the presence of xenon bisperfluoroalkylcarboxylates. At the interaction of these compounds with potassium et

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.
