Trisulfur dichloride, also known as S2Cl2, is a chemical compound consisting of two sulfur atoms and two chlorine atoms. It is a colorless, volatile, and highly toxic liquid with a pungent odor. Trisulfur dichloride is used as a reagent in organic synthesis, particularly in the preparation of various sulfur-containing compounds. It is also employed as a chlorinating and sulfurating agent in chemical reactions. Due to its hazardous nature, trisulfur dichloride requires careful handling and storage, and it is essential to follow proper safety protocols when working with this substance.

Check Digit Verification of cas no

The CAS Registry Mumber 31703-09-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,7,0 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 31703-09:
(7*3)+(6*1)+(5*7)+(4*0)+(3*3)+(2*0)+(1*9)=80
80 % 10 = 0
So 31703-09-0 is a valid CAS Registry Number.

Preparation, Crystal Structure, and Vibrational Spectra of cyclo-Undecasulfur (S11) and of cyclo-Tridecasulfur (S13)

Steudel, Ralf,Steidel, Juergen,Sandow, Torsten

, p. 958 - 970 (2007/10/02)

The homocyclic S11 and S13 molecules have been synthesized from titanocenepentasulfide and S6Cl2 or S8Cl2, respectively, and obtained as yellow crystals which are metastable for several days at 20 deg C.X-Ray structural analyses of single crystals at -105+/-5 deg C exhibited molecules of approximately C2 symmetry with bond distances (d), bond angles (α) and torsional angles (τ) in the following ranges: S11: d = 203.2-211.0 pm, α = 103.3-108.6 deg, τ = 69.3-140.5 deg; S13: d = 197.8-211.3 pm, α = 102.8-111.1 deg, τ = 29.5-116.3 deg.Infrared and Raman spectra of S11 and S13 are reported.In addition, the synthesis of S6Cl2 and S8Cl2 from S6 or S8, respectively, and chlorine is described. - Key words: Elemental Sulfur, Sulfur Rings, Crystal Structure, Raman Spectra, IR Spectra
