2721-32-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2721-32-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,2 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2721-32:
(6*2)+(5*7)+(4*2)+(3*1)+(2*3)+(1*2)=66
66 % 10 = 6
So 2721-32-6 is a valid CAS Registry Number.

Synthesis and reactions of 2,3-diazabicyclo[2.2.1]hept-5-ene
Wang,Sheridan
, p. 5673 - 5676 (2007/10/02)
The first synthesis of 2,3-diazabicyclo[2.2.1]hept-5-ene is reported. The generation of this molecule is facilitated by the isolation of the bis-carboxylate salt formed on hydrolysis of the corresponding biscarbamate. The retro-Diels-Alder generation of diimide and cyclopentadiene is explored.
