74524-55-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74524-55-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,5,2 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 74524-55:
(7*7)+(6*4)+(5*5)+(4*2)+(3*4)+(2*5)+(1*5)=133
133 % 10 = 3
So 74524-55-3 is a valid CAS Registry Number.

Heats of Hydrogenation, II. Heats of Hydrogenation of Bicyclopent-2-ene, an Antiaromatic System

Roth, Wolfgang R.,Klaerner, Frank-Gerrit,Lennartz, Hans-Werner

, p. 1818 - 1829 (2007/10/02)

The heat of hydrogenation of the olefinic double bond in bicyclopent-2-ene (2) and in the 5,5-dimethyl derivative 22 has been determined (42.5 and 42.0 kcal mol-1).By comparison with the heat of hydrogenation of the double bond in bicyclohex-2-ene (10) and bicyclohept-6-ene (9) an antiaromatic destabilisation of 10 kcal mol-1 is demonstrated.The antiaromaticity of 2 is also manifested in its high dienophilic reactivity.The rate of the reaction of 2 with 1,3-cyclopentadiene (6) is enhanced by a factor of 4.5 * 104 compared to the analogous reaction of bicyclooct-7-ene (8).
