Sebacoguanamine, also known as 1,8-octanediamine, is an organic compound with the chemical formula C8H20N2. It is a colorless liquid that is soluble in water and serves as an important intermediate in the production of various chemicals, including nylon-6,6, a type of synthetic polymer used in textiles, plastics, and other materials. Nylon-6,6 is created through a condensation reaction between sebacoyl chloride and sebacoguanamine, which are derived from the same starting material, sebacic acid. Sebacoguanamine plays a crucial role in the synthesis of this widely used polymer, contributing to its strength, durability, and versatility in various applications.
The CAS Registry Mumber 4128-90-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,2 and 8 respectively; the second part has 2 digits, 9 and 0 respectively. Calculate Digit Verification of CAS Registry Number 4128-90: (6*4)+(5*1)+(4*2)+(3*8)+(2*9)+(1*0)=79 79 % 10 = 9 So 4128-90-9 is a valid CAS Registry Number.
