649-48-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 649-48-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 649-48:
(5*6)+(4*4)+(3*9)+(2*4)+(1*8)=89
89 % 10 = 9
So 649-48-9 is a valid CAS Registry Number.

Dialkyltin(IV) difluorides: Synthesis and study of their state in solutions

Kokunov,Ershova,Rakov,Sakharov

, p. 608 - 610 (2008/10/08)

Dialkyltin difiuorides Bu2SnF2 and Et2SnF2 were synthesized by reacting R2SnO with hydrofluoric acid and heating. Solutions of Bu2SnF2 and Bu2SnCl2 in different organic solvents were studied by 119Sn, 19F, 13C, and 1H NMR spectroscopy. The conclusion is drawn that dialkyltin dihalides partially dissociate in solutions.
