6731-22-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6731-22-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,3 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6731-22:
(6*6)+(5*7)+(4*3)+(3*1)+(2*2)+(1*2)=92
92 % 10 = 2
So 6731-22-2 is a valid CAS Registry Number.

THERMAL REARRANGEMENTS OF CYCLIC ALLENES via RETRO-ENE REACTIONS
Price, John D.,Johnson, Richard P.
, p. 2499 - 2502 (2007/10/02)
Flow vacuum thermolysis (500-650 deg C) of 1,2-cyclonona- and 1,2-cyclodecadienes yields, as primary products, terminal enynes and enedienes.Secondary intramolecular Diels-Alder reactions of the enedienes afford cis and trans bicyclics.
