Check Digit Verification of cas no

The CAS Registry Mumber 1370529-58-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,0,5,2 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1370529-58:
(9*1)+(8*3)+(7*7)+(6*0)+(5*5)+(4*2)+(3*9)+(2*5)+(1*8)=160
160 % 10 = 0
So 1370529-58-0 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).

Photochemical studies on aromatic γ,δ-epoxy ketones: Efficient synthesis of benzocyclobutanones and indanones

Shao, Yutian,Yang, Chao,Gui, Weijun,Liu, Yang,Xia, Wujiong

, p. 3560 - 3562 (2012/06/04)

Irradiation of terminal aromatic γ,δ-epoxy ketones with a 450 W UV lamp led to Norrish type II cyclization/semi-pinacol rearrangement cascade reaction which formed the benzocyclobutanones containing a full-carbon quaternary center, whereas irradiation of substituted aromatic γ,δ-epoxy ketones led to the indanones through a photochemical epoxy rearrangement and 1,5-biradicals cyclization tandem reaction.
