1544-84-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1544-84-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,4 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1544-84:
(6*1)+(5*5)+(4*4)+(3*4)+(2*8)+(1*4)=79
79 % 10 = 9
So 1544-84-9 is a valid CAS Registry Number.

ORGANYLISOCYANIDDIFLUORIDE R-N=CF2 DURCH DIREKTFLUORIERUNG VON ISOCYANIDEN
Ruppert, Ingo
, p. 4893 - 4896 (2007/10/02)
Interaction of elemental fluorine with isocyanides yields predominantly isocyanide difluorides without destruction of the organic periphery.Their stereodynamic behaviour was studied by combined 19F- and 13C-NMR experiments.
