Check Digit Verification of cas no
The CAS Registry Mumber 36439-78-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,4,3 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 36439-78:
(7*3)+(6*6)+(5*4)+(4*3)+(3*9)+(2*7)+(1*8)=138
138 % 10 = 8
So 36439-78-8 is a valid CAS Registry Number.

Charge-Transfer Complexes and Reactivity in Diels-Alder Cycloadditions
Sustmann, Reiner,Dern, Mechthild,Kasten, Ronald,Sicking, Willi
, p. 1315 - 1322 (2007/10/02)
The reactivity of 2,3-bis(methylene)norbornane (1) towards the highly reactive dienophiles 2,3-dicyano-p-benzoquinone (2), tetracyanoethylene (3), 2,3-dicyanomaleimide (4), and p-benzoquinone-2,3-dicarboxyclic anhydride (5) was analysed kinetically.CT complexes were observed for 1 with 2-5 and equilibrium constants for the formation of the CT complexes between 1 and 2-4 were determined kinetically.The relationship between relative rates, CT-excitation energies, HOMO-LUMO separations, and CT-complex equilibrium constants is discussed.The results do not require the CT complexes to be intermediates but strongly support the importance of CT interactions in the transition state of these cycloadditions.
