Check Digit Verification of cas no

The CAS Registry Mumber 138689-12-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,6,8 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138689-12:
(8*1)+(7*3)+(6*8)+(5*6)+(4*8)+(3*9)+(2*1)+(1*2)=170
170 % 10 = 0
So 138689-12-0 is a valid CAS Registry Number.

Intramolecular photocycloaddition of β-stilbazoles tethered by silyl chains

Maeda, Hajime,Hiranabe, Ryu-ichiro,Mizuno, Kazuhiko

, p. 7865 - 7869 (2006)

Intramolecular (2+2) photocycloaddition of β-stilbazoles tethered by silyl chains took place with high efficiency. Complexation with dicarboxylic acid or catechol further enhanced both the efficiency and stereoselectivity.

Synthesis of silicon-containing macrocyclic compounds by using intramolecular [2+2] photocycloaddition reactions of bis-dimethylsilyl-linked styrenes and stilbenes

Maeda, Hajime,Nishimura, Ko-ichi,Hiranabe, Ryu-ichiro,Mizuno, Kazuhiko

, p. 472 - 477 (2018/07/03)

A method for the synthesis of silicon-containing macrocyclic compounds, using intramolecular [2 + 2] photocycloaddition reactions of bis-dimethylsilyl-linked styrene or stilbene derivatives, is described. Photoirradiation of benzene solutions of o- and m-

Synthesis and photochemical properties of stilbenophanes tethered by silyl chains. Control of (2π + 2π) photocycloaddition, cis-trans photoisomerization, and photocyclization

Maeda, Hajime,Nishimura, Ko-Ichi,Mizuno, Kazuhiko,Yamaji, Minoru,Oshima, Juro,Tobita, Seiji

, p. 9693 - 9701 (2007/10/03)

Novel macrocyclic and medium-size stilbenophanes tethered by silyl chains were synthesized, and their photochemical and photophysical properties were examined. Direct photoirradiation of macrocyclic stilbenophanes gave intramolecular photocycloadducts ste
