5447-80-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5447-80-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,4 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5447-80:
(6*5)+(5*4)+(4*4)+(3*7)+(2*8)+(1*0)=103
103 % 10 = 3
So 5447-80-3 is a valid CAS Registry Number.

Chemiluminescence during thermolysis of the (Ph3COOCPh3)n-Ph3C. peroxide containing captured triphenylmethyl radical

Bulgakov,Kuleshov,Sharapova,Sadykov,Khursan

, p. 1194 - 1197 (2007/10/03)

Chemiluminescence (CL) in the thermolysis of (Ph3COOCPh3)n-Ph3C. containing the triphenylmethyl radical captured during the synthesis of Gomberg's peroxide was found. Two CL emitters were identified: the triplet state of benzophenone (3Ph2CO*) and Ph3C.*. Ph3C.* is formed due to the energy transfer from the excited 3Ph2CO* generated in the disproportion of thermolysis intermediates, Ph3CO. radicals. This Ph3C.* luminescence is the first example of CL activation by an organic radical. Chemiluminescence during the thermolysis of Ph3COOCPh3 containing no Ph3C. is resulted from the emission of one emitter, 3Ph2CO*. The solid-phase CL was found during the oxidation of Ph3C. with dioxygen after the destruction of the crystalline lattice as a result of the thermolysis of the (Ph3COOCPh3)n-Ph3C. peroxide.
