17044-52-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 17044-52-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,0,4 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 17044-52:
(7*1)+(6*7)+(5*0)+(4*4)+(3*4)+(2*5)+(1*2)=89
89 % 10 = 9
So 17044-52-9 is a valid CAS Registry Number.

Photolysis of dibenzo[a,d]cycloheptene dimer
Chang, Meng-Yang,Huang, Yu-Ping
, p. 632 - 638 (2013/10/22)
Photolysis reaction of dibenzo[a,d]cycloheptene dimer 3 provides three dibenzo[a,d]cycloheptyl dimmers 4, 5 and 6 under different irradiation conditions via the intramolecular degradative cyclodimerization. A tetracyclic benzo[4,5]cyclohepta[1,2,3-de]naphthalene core is also synthesized.
