7384-19-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7384-19-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,8 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7384-19:
(6*7)+(5*3)+(4*8)+(3*4)+(2*1)+(1*9)=112
112 % 10 = 2
So 7384-19-2 is a valid CAS Registry Number.

REVERSE MUMM REARRANGEMENTS. I. THERMOLYSIS OF 3-ACETOXY-1-FORMYLINDAZOLE

Dumitrascu, Florea,Raileanu, Dan

, p. 1247 - 1258 (2007/10/03)

2-Acetyl-3-indazolone (15), 1,2-diacetyl-3-indazolone (16) and 3-acetoxy-1-acetylindazole (3) are intermediates of the title thermolysis which leads to 1-acetyl-3-indazolone (4). The rearrangement of 16 to 3 is a reverse Mumm rearrangement which has not yet been observed. The same pattern applies to the acetylation of the 3-indazolone (2). Acylotropic equilibria have been observed between 2-acetyl-1-methyl-3-indazolone (24) and 3-acetoxy-1-methylindazole (26).

Acyl Derivatives of Indazolin-3-one

Anderson, Robert M.

, p. 3933 - 3959 (2007/10/02)

1- and 2-Ethanoyl-, propanoyl-, butanoyl- and benzoylindazolin-3-ones have been prepared and the 2-isomers have been shown to exist in two tautomeric forms.Sulphonylation and further acylation of these compounds are described and some rearrangements in the series are discussed.
