Check Digit Verification of cas no
The CAS Registry Mumber 917-89-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,1 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 917-89:
(5*9)+(4*1)+(3*7)+(2*8)+(1*9)=95
95 % 10 = 5
So 917-89-5 is a valid CAS Registry Number.

Sulfuranonium Ions, R-SF4+, Preparation, Evidence, and Stability
Wessel, Juergen,Kleemann, Gert,Seppelt, Konrad
, p. 2399 - 2407 (2007/10/02)
Sulfuranonium Ions of the type R-SF4+ are generated from R-SF5 by fluoride ion abstraction with SbF5.In spite of large variation of R (CH3, CH=CH2, CCH a. o.) none of the ions is stable at room temperature.The ions were identified by NMR met
