55720-38-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55720-38-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,7,2 and 0 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 55720-38:
(7*5)+(6*5)+(5*7)+(4*2)+(3*0)+(2*3)+(1*8)=122
122 % 10 = 2
So 55720-38-2 is a valid CAS Registry Number.

The photochemistry of three tetrachloronaphthalenes
Freeman, Peter K.,Clapp, Gary E.,Stevenson, Brian K.
, p. 5705 - 5708 (2007/10/02)
The regiochemistry of the photolysis of three tetrachloronaphthalenes is sharply dependent upon the presence of triethylamine. Analysis of the steady state kinetics in the presence and absence of quenchers and triethylamine provides a mechanistic rationale in terms of triplet, triplet excimer, and singlet exciplex.
