3-Oxa-spiro[5.6]dodecane-2,4-dione, also known as spiro[5.6]dodecane-2,4-dione, is a cyclic ketone with a unique spiro structure. It consists of a 12-membered ring with a spiro carbon atom connecting two six-membered rings, one of which contains an oxygen atom, forming a 3-oxa group. The molecule has two carbonyl groups, one at the 2-position and the other at the 4-position, which contribute to its reactivity and potential applications in organic synthesis. 3-OXA-SPIRO[5.6]DODECANE-2,4-DIONE is of interest to chemists due to its structural complexity and the challenges it presents in synthesis and functionalization. It may be used as a building block in the creation of more complex molecules or as a precursor in the synthesis of pharmaceuticals and other specialty chemicals.

4432-19-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4432-19-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,3 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4432-19:
(6*4)+(5*4)+(4*3)+(3*2)+(2*1)+(1*9)=73
73 % 10 = 3
So 4432-19-3 is a valid CAS Registry Number.
