921-12-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 921-12-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,2 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 921-12:
(5*9)+(4*2)+(3*1)+(2*1)+(1*2)=60
60 % 10 = 0
So 921-12-0 is a valid CAS Registry Number.

Action of atomic fluorine on E- and Z-2-butene

Bumgardner, Carl L.,Carver, James G.

, p. 331 - 338 (2007/10/02)

Irradiation of N2F4(NF2) with E- and Z-2 butene in the gas phase leads to addition of F and NF2 across the double bond in a non-stexeoselective manner and abstraction of H to give 2- butenyl radicals which interconvert rapidly before being trapped by NF2 to yield E- and Z-1- difluoroamino-2-butene and 3-difluoramino-1-butene. The configurational instability of the 2- butenyl radicals is attributed to the exothermicity of F atom abstraction. These results are contrasted with those of other workers who observed that in condensed phase reactions abstraction by t-butoxy radical leads to 2-butenyl radicals which are configurationally stable.
