Tetra-O-acetyl-galactonsaeure-dianilid, also known as Tetra-O-acetyl-D-galacturonic acid dianilide, is a chemical compound derived from D-galacturonic acid, a key component of pectin found in plants. Tetra-O-acetyl-galactonsaeure-dianilid is characterized by the presence of four acetyl groups attached to the hydroxyl groups of the galacturonic acid molecule, which are then linked to two aniline molecules, forming an amide bond. The acetyl groups protect the hydroxyl groups, making the molecule more stable and less reactive. Tetra-O-acetyl-galactonsaeure-dianilid is often used in organic synthesis and as a starting material for the preparation of various galactose derivatives, which have applications in pharmaceuticals, food science, and other industries.
The CAS Registry Mumber 5160-18-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,6 and 0 respectively; the second part has 2 digits, 1 and 8 respectively. Calculate Digit Verification of CAS Registry Number 5160-18: (6*5)+(5*1)+(4*6)+(3*0)+(2*1)+(1*8)=69 69 % 10 = 9 So 5160-18-9 is a valid CAS Registry Number.
