73406-52-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 73406-52-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,4,0 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 73406-52:
(7*7)+(6*3)+(5*4)+(4*0)+(3*6)+(2*5)+(1*2)=117
117 % 10 = 7
So 73406-52-7 is a valid CAS Registry Number.

Regioselective Fluorination of Acenes: Tailoring of Molecular Electronic Levels and Solid-State Properties

Bischof, Daniel,Tripp, Matthias W.,Hofmann, Philipp E.,Ip, Chun-Ho,Ivlev, Sergei I.,Gerhard, Marina,Koert, Ulrich,Witte, Gregor

, (2022/01/08)

Optoelectronic properties of molecular solids are important for organic electronic devices and are largely determined by the adopted molecular packing motifs. In this study, we analyzed such structure-property relationships for the partially regioselectiv

Hydrogen-atom abstraction/cyclization in synthesis. Direct syntheses of coumestan and coumestrol

Kraus, George A.,Zhang, Ning

, p. 5644 - 5646 (2007/10/03)

The synthesis of coumestrol has been achieved in five steps from 1,3-dimethoxybenzene. The key step is a photochemical cyclization of a glyoxylate ester.

The direct synthesis of isoflavans VIA α-alkylation of phenylacetates

Versteeg, Marietjie,Bezuidenhoudt, Barend C. B.,Ferreira, Daneel

, p. 1373 - 1394 (2007/10/03)

Deprotonation of oxygenated phenylacetates and quenching of the enolates with oxygenated benzylic electrophiles, afforded 2,3-diarylpropanoates which served as precursors to the isoflavans following consecutive reduction and cyclization steps.
