51559-36-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 51559-36-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,5,5 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 51559-36:
(7*5)+(6*1)+(5*5)+(4*5)+(3*9)+(2*3)+(1*6)=125
125 % 10 = 5
So 51559-36-5 is a valid CAS Registry Number.

13C NMR Spectral Studies of Some Methoxycoumarin Derivatives. A Re-assignment for Citropten (Limettin) and an Examination of Peri-Proximity Effects for the Methyl-Methoxy and Methoxy-Methyl Couples

Osborne, Alan G.

, p. 348 - 354 (1989)

The 13C chemical shifts and 13C-1H coupling constants of some methoxycoumarins are reported.Some earlier spectral assignments, including those for citropten (limettin), require revision.Methoxy substituent effects on long-range 13C-1H couplings in coumarins are highlighted.Peri-proximity effects for the methyl-methoxy and mehoxy-methyl couples are derived, and the value of these effects in the assignment of peri-substituted compounds is illustrated.

Process for preparing coumarin derivatives using phenol and propiolic acid

-

Paragraph 0119; 0120, (2017/01/12)

Provided is a manufacturing method of coumarin derivative. The manufacturing method of coumarin derivative comprises a step of making a phenol compound react with a propiolic acid compound. According to the present invention, the manufacturing method of coumarin derivative is quick and efficient, and is useful to fields requiring synthesis of coumarin derivatives of various structures.COPYRIGHT KIPO 2016

Improved synthesis of coumarins by iron(III)-catalyzed cascade reaction of propiolic acids and phenols

Kutubi, Md. Shahajahan,Hashimoto, Takuya,Kitamura, Tsugio

experimental part, p. 1283 - 1289 (2011/05/19)

The reaction of propiolic acids with phenols in the presence of FeClAgOTf catalyst proceeded efficiently in a mixed solvent of trifluoroacetic acid and 1,2-dichloroethane, and provided coumarins in good to high yields. This iron-catalyzed reaction offers a much-improved synthesis of coumarins. Thieme Stuttgart New York.
