63585-72-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 63585-72-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,5,8 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 63585-72:
(7*6)+(6*3)+(5*5)+(4*8)+(3*5)+(2*7)+(1*2)=148
148 % 10 = 8
So 63585-72-8 is a valid CAS Registry Number.

Synthesis of 3-Ferrocenyl Isocoumarins

Sinha, Neeta

, p. 976 - 979 (2020/11/25)

The derivatives of 3-ferrocenyl isocoumarin were synthesized by the condensation of substituted homothphalic anhydride with ferrocene using phosphoric acid or anhydrous aluminium chloride as cyclising agent. Substituted homophthalic acid did not condense with ferrocene so homophthalic acids were converted into their anhydride and then allowed to react with ferrocene in the presence of polyphosphoric acid or in the presence of anhydrous aluminium chloride using dichloromethane as the solvent to give 3-ferrocenyl isocoumarins. 7-Methoxy, 6-methyl, 5,7-dihydroxy, 6,7-dimethoxy and 5,7-dimethoxy derivatives of 3-ferrocenyl isocoumarin were synthesized. All the compounds were characterised by melting point determination, elemental and spectral analysis.
