Furcellaran, also known as Danish agar, is a hydrocolloid extracted from the red seaweed Furcellaria fastigiata. It is a brownish, tan, or white powder that is odorless and has a mucilaginous taste. Furcellaran is soluble in water at temperatures around 80°C, forming a viscous, clear, or slightly opalescent solution. It consists mainly of potassium, sodium, magnesium, calcium, and ammonium sulfate esters of galactose and 3,6-anhydrogalactose copolymers, with an ester sulfate content ranging from 8% to 20%. The relative proportion of cations in Furcellaran may change during processing, and it is recovered by alcohol precipitation, potassium precipitation, or freezing. Used in Food Industry: Furcellaran is used as a natural colloid, gelling agent, and viscosity control agent in various food products. It is particularly used in milk puddings, flans, jelly, jam, and gelled meat products due to its thermoreversible gels that form after heating and cooling, exhibiting properties between agar and carrageenan. Used in Pharmaceutical Industry: Furcellaran is utilized as a gelling agent and viscosity control agent in pharmaceuticals, including products for diabetics and proprietary weight loss supplements. Used in Oral Care Products: In the oral care industry, Furcellaran serves as a gelling agent and viscosity control agent in toothpastes. Used in Preservatives and Bactericides: Furcellaran acts as a carrier for food preservatives and bactericides, enhancing their effectiveness in various applications. Used in Bacteriological Culture Media: Furcellaran is employed as a gelling agent in bacteriological culture media, providing a stable and suitable environment for bacterial growth. Agricultural Uses: Furcellaria fastigiata, the source of Furcellaran, is harvested in Denmark and is commonly referred to as Danish agar.

Check Digit Verification of cas no
The CAS Registry Mumber 9000-21-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,0 and 0 respectively; the second part has 2 digits, 2 and 1 respectively. Calculate Digit Verification of CAS Registry Number 9000-21: (6*9)+(5*0)+(4*0)+(3*0)+(2*2)+(1*1)=59 59 % 10 = 9 So 9000-21-9 is a valid CAS Registry Number.
