122821-76-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 122821-76-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,8,2 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 122821-76:
(8*1)+(7*2)+(6*2)+(5*8)+(4*2)+(3*1)+(2*7)+(1*6)=105
105 % 10 = 5
So 122821-76-5 is a valid CAS Registry Number.

Thermal Rearrangement of N-Arylmethyl- and N-Alkyl-2,2-dihalogenocyclopropyl Imines

Kagabu, Shinzo,Ando, Chihaya,Ando, Junko

, p. 739 - 752 (2007/10/02)

An extended study of the thermal isomerization of 1-substituted 2,2-dihalogenocyclopropyl imines is reported.The thermolysis of N-arylmethyl-2,2-dichlorocyclopropanecarbaldimines 15a-h produces 2-aryl- 16a-h and 2-aryl-4-chloro-pyridine derivatives 17a-h, while N-cyclopropyl imines 15i, j yielded N-alyklchloropyrroles.The 2,2-dibromocyclopropane analogue undergoes thermolysis at lower temperatures.An ionic mechanism triggered by the halide ion dissociation is proposed for the thermal rearrangement on the basis of a study using deuterated imine 15m, and the effects of additives and solvents.On the other hand, difluorocyclopropyl imine undergoes a homolytic cleavage of cyclopropane 1,3-bond with lower activation energy than the dichlorocyclopropyl imine, and afforded the N-alykl-3-fluoropyrrole derivative preferentially.
