The CAS Registry Mumber 1413394-06-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,3,3,9 and 4 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1413394-06:
(9*1)+(8*4)+(7*1)+(6*3)+(5*3)+(4*9)+(3*4)+(2*0)+(1*6)=135
135 % 10 = 5
So 1413394-06-5 is a valid CAS Registry Number.

Cyclization of (2-alkenylphenyl)carbonyl compounds to polycyclic arenes catalyzed by copper(II) trifluoromethanesulfonate or trifluoromethanesulfuric acid

Liu, Wei-Min,Tnay, Ya Lin,Gan, Kian Ping,Liu, Zhen-Hong,Tyan, Wan Huei,Narasaka, Koichi

, p. 1953 - 1969,17 (2012/12/12)

Various polycyclic arenes, such as naphthalenes, tetrahydroantharacenes, tetrahydrotetracenes, dihydropentacenes, and dihydropentaphenes are prepared from 2-alkenylphenyl ketones and aldehydes by the catalytic use of copper(II) trifluoromethanesulfonate (Cu(OTf)2) or trifluoromethanesulfuric acid (TfOH).
