83505-21-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 83505-21-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,0 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 83505-21:
(7*8)+(6*3)+(5*5)+(4*0)+(3*5)+(2*2)+(1*1)=119
119 % 10 = 9
So 83505-21-9 is a valid CAS Registry Number.

SYNTHESIS AND INTRAMOLECULAR CYCLISATION OF ortho-HYDROXY-2,3,3,3-TETRAFLUOROPROPIOPHENONE. FORMATION OF 3-FLUORO-4-HYDROXYCOUMARIN

Dmowski, Wojciech

, p. 589 - 598 (1982)

Acidic hydrolysis of 1-(o-methoxyphenyl)pentafluoropropene 1 gave o-hydroxy-2,3,3,3-tetrafluoropropiophenone 2 and o-methoxy-2,3,3,3-tetrafluoropropiophenone 3.Compound 2 when treated with aqueous potassium hydroxide or methanolic sodium methoxide gave 3-fluoro-4-hydroxycoumarin 4.Structure of 4 has been established by spectral means and some chemical reactions.The cyclisation mechanism of 2 is discussed.
