34814-77-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 34814-77-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,8,1 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 34814-77:
(7*3)+(6*4)+(5*8)+(4*1)+(3*4)+(2*7)+(1*7)=122
122 % 10 = 2
So 34814-77-2 is a valid CAS Registry Number.

Domino Dehydrative π-Extension: A Facile Path to Extended Perylenes and Terrylenes

Akhmetov, Vladimir,Amsharov, Konstantin,Feofanov, Mikhail

supporting information, p. 17322 - 17325 (2021/11/16)

Herein, we report a new method for synthesis of extended perylenes and terrylenes. The technique is based on the cascade dehydrative π-extensions (DPEX) of aryl aldehydes, in which stepwise annulations activate previously “dormant” substituents. Two- and fourfold cyclizations of 3-aryl-biphenyl-2,2′-dicarbaldehydes offer a rapid path to unsymmetrical perylenes and elusive terrylene derivatives, respectively. DPEX of 3,3′′-(phenanthrene-1,8-diyl)bis (([1,1′-biphenyl]-2,2′-dicarbaldehyde)) leads to the biradical structure, which proceeds in situ into oxidative electrocyclization at room temperature. The described domino process complements and expands DPEX approach to a large family of fused acenes and related PAHs.
