89780-89-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 89780-89-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,8 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 89780-89:
(7*8)+(6*9)+(5*7)+(4*8)+(3*0)+(2*8)+(1*9)=202
202 % 10 = 2
So 89780-89-2 is a valid CAS Registry Number.

1,3-Cyclopentanediyls - Intermediates or Transition States?

Roth, Wolfgang R.,Bauer, F.,Breuckmann, Rolf

, p. 2041 - 2046 (2007/10/02)

The energy well of the singlet diradicals 4a and 6 has been determined by the oxygen trapping technique to be 2.7 and 1.9 kcal/mol, respectively.From the oxygen and temperature dependence of the trapping rate of the diradical 4a activation barriers of 2.2 and 4.9 kcal/mol have been derived for the mutual interconversion of the spin isomers with the triplet being the ground state. Key Words: 1,3-Diradicals, energy well, singlet-triplet splitting / 1,3-Cyclopentanediyls

PREPARATIVE UV-LASER PHOTOCHEMISTRY OF THE AZOALKANE SPIRO(2,3-DIAZABICYCLOHEPT-2-ENE-7',1-CYCLOPROPANE): TRAPPING OF THE 1,4-DIRADICAL 2-(3-CYCLOPENTENYL)ETHYL BY MOLECULAR OXYGEN

Adam, Waldemar,Hannemann, Klaus,Hoessel, Peter

, p. 181 - 184 (2007/10/02)

Photo-extrusion of nitrogen from the azoalkane 1 in the presence of molecular oxygen gave besides the hydrocarbons 3 and 5, the endoperoxide 10 and hydroperoxide 11, the former via trapping of the 1,4-diradical 4 by triplet oxygen, the latter by ene-reaction of hydrocarbon 5 with singlet oxygen.
