Check Digit Verification of cas no
The CAS Registry Mumber 13520-79-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,2 and 0 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13520-79:
(7*1)+(6*3)+(5*5)+(4*2)+(3*0)+(2*7)+(1*9)=81
81 % 10 = 1
So 13520-79-1 is a valid CAS Registry Number.

The compound WSF4 was synthesized in one step by the reaction of WF6 with (Me3Si)2S in solution at ambient temperatures. Solution-phase structural data have been obtained for the first time for it and related tungsten chalcogenide tetrahalides via a tungsten L(III)-edge EXAFS (extended X-ray absorption fine structure) study. This demonstrates that WOF4, WOCl4 and WSF4 in acetonitrile or dichloromethane solution are monomeric. For WSF4 analysis of the EXAFS data yielded bond lengths of 2.026(8) (W=S) and 1.863(3) A (W-F). The W=S bond length is shorter than previously determined, by gas-phase electron diffraction, but is more consistent with that found in related structures.
