153-31-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 153-31-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,5 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 153-31:
(5*1)+(4*5)+(3*3)+(2*3)+(1*1)=41
41 % 10 = 1
So 153-31-1 is a valid CAS Registry Number.

Revisiting Kekulene: Synthesis and Single-Molecule Imaging

Pozo, Iago,Majzik, Zsolt,Pavli?ek, Niko,Melle-Franco, Manuel,Guitián, Enrique,Pe?a, Diego,Gross, Leo,Pérez, Dolores

, p. 15488 - 15493 (2019)

Four decades after the first (and only) reported synthesis of kekulene, this emblematic cycloarene has been obtained again through an improved route involving the construction of a key synthetic intermediate, 5,6,8,9-tetrahydrobenzo[m]tetraphene, by means of a double Diels-Alder reaction between styrene and a versatile benzodiyne synthon. Ultra-high-resolution AFM imaging of single molecules of kekulene and computational calculations provide additional support for a molecular structure with a significant degree of bond localization in accordance with the resonance structure predicted by the Clar model.
