Check Digit Verification of cas no

The CAS Registry Mumber 1030375-08-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,0,3,7 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1030375-08:
(9*1)+(8*0)+(7*3)+(6*0)+(5*3)+(4*7)+(3*5)+(2*0)+(1*8)=96
96 % 10 = 6
So 1030375-08-6 is a valid CAS Registry Number.

Thermal [2 + 2]-cycloaddition between silylalkynes and allenylphenols followed by the nucleophilic addition of water: Metal-free and economical synthesis of arylcyclobutenals

Ohno, Shohei,Avena, Ramon Francisco,Aoyama, Hiroshi,Fujioka, Hiromichi,Arisawa, Mitsuhiro

, p. 1220 - 1228 (2020/03/11)

Herein, we report an unprecedented thermal [2 + 2]-cycloaddition between silylalkynes and allenylphenols to form an aromatizing cyclobutachromene intermediate, followed by the nucleophilic addition of water to yield functionalized arylcyclobutenals. This reaction is atom- and pot-economical because all the atoms contained in the starting material are retained in the final product, no other reactants are required, and it proceeds in one-pot.

Intermolecular and intramolecular pauson-khand reactions of functionalized Allenes

Gonzalez-Gomez, Alvaro,Anorbe, Loreto,Poblador, Amalia,Dominguez, Gema,Perez-Castells, Javier

supporting information; experimental part, p. 1370 - 1377 (2009/04/11)

Pauson-Khand reactions of functionalized allenes with different alkynes give cyclopentenones with generally high regio-and stereoselectivities. The allenes react through their external double bonds, giving cyclopentenones with exocyclic double bond at their β positions and predominantly with E stereochemistry. Some intramolecular reactions with allenynes connected through aromatic rings are described. These give the corresponding heterocycles with moderate to good yields. Wiley-VCH Verlag GmbH & Co.
