56535-19-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 56535-19-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,5,3 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 56535-19:
(7*5)+(6*6)+(5*5)+(4*3)+(3*5)+(2*1)+(1*9)=134
134 % 10 = 4
So 56535-19-4 is a valid CAS Registry Number.

SOLVOLYSIS REACTIONS OF BIS(DIFLUORAMINO)ETHYLENES: A ROUTE TO NITRENIUM IONS
Graham, William H.
, p. 319 - 330 (2007/10/02)
The reaction of tetrafluorhydrazine with acetylenes in inert solvent gives α,α-(fluorodifluoramino)fluorimines via unstable bis(difluoramino)ethylenes.Under solvolytic conditions the rearrangement involves Sn1 cleavage of the N-F bond and the formation of
