1028333-71-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1028333-71-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,8,3,3 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1028333-71:
(9*1)+(8*0)+(7*2)+(6*8)+(5*3)+(4*3)+(3*3)+(2*7)+(1*1)=122
122 % 10 = 2
So 1028333-71-2 is a valid CAS Registry Number.

Bronsted acid TfOH-mediated [3 + 2] cycloaddition reactions of diarylvinylidenecyclopropanes with nitriles
Li, Wei,Shi, Min
, p. 4151 - 4154 (2008/09/21)
(Chemical Equation Presented) Diarylvinylidenecyclopropanes undergo a [3 + 2] cycloaddition reaction with MeCN in the presence of Bronsted acid TfOH to give the corresponding 3,4-dihydro-2H-pyrrole derivatives 2 in moderate to excellent yields under reflu
