Check Digit Verification of cas no
The CAS Registry Mumber 7791-16-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,9 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7791-16:
(6*7)+(5*7)+(4*9)+(3*1)+(2*1)+(1*6)=124
124 % 10 = 4
So 7791-16-4 is a valid CAS Registry Number.

Reactivity of antimony mixed halides for the flourination of tetrachlorethene (PCE) in liquid phase
Brunet,Batiot,Moriceau,Thybaud
, p. 183 - 186 (2008/10/09)
The active species for the liquid phase fluorination of tetrachloroethene (PCE) was produced by in situ reaction between HF and SbCl5. By comparison with various commercial antimony mixed halides (SbCl4F, SbCl3F2, SbCl2F3 and SbClF4), the active species, produced in situ in our conditions, could be composed by SbCl4F or/and SbCl3F2 or a mixture of both.
