Sodium 5,6,7,8-tetrahydronaphthalene-2-sulphonate, also known as sodium naphthalene-2-sulfonate, is a chemical compound with the molecular formula C10H9NaO3S. It is a white crystalline solid that is soluble in water and is commonly used as a surfactant, particularly in the petroleum industry for enhanced oil recovery. sodium 5,6,7,8-tetrahydronaphthalene-2-sulphonate is also employed as a detergent, wetting agent, and dispersing agent in various applications. It is derived from naphthalene, a polycyclic aromatic hydrocarbon, and its sulfonation at the 2-position followed by neutralization with sodium hydroxide results in the formation of the sodium salt. Due to its surfactant properties, it can reduce surface tension and improve the efficiency of oil extraction from reservoirs.

135-80-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 135-80-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 135-80:
(5*1)+(4*3)+(3*5)+(2*8)+(1*0)=48
48 % 10 = 8
So 135-80-8 is a valid CAS Registry Number.
