Chlorolignin is a complex organic polymer derived from the kraft lignin, a byproduct of the paper pulping process. It is formed by the reaction of lignin with chlorine, which modifies its structure and properties. Chlorolignin is characterized by its dark brown color and high molecular weight, and it exhibits improved solubility and reactivity compared to its parent lignin. This chemical is used in various applications, including the production of adhesives, resins, and polymers, as well as in the manufacturing of chemicals like vanillin and lignosulfonates. Due to its chlorine content, chlorolignin is considered less environmentally friendly than other lignin derivatives, and there is ongoing research to find more sustainable uses for this material.
The CAS Registry Mumber 8068-02-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,6 and 8 respectively; the second part has 2 digits, 0 and 2 respectively. Calculate Digit Verification of CAS Registry Number 8068-02: (6*8)+(5*0)+(4*6)+(3*8)+(2*0)+(1*2)=98 98 % 10 = 8 So 8068-02-8 is a valid CAS Registry Number.
