67990-78-7 Usage
General Description
PERFLUORO(2-ETHOXYETHANE)SULFONYL FLUORIDE, also known as Fomblin perfluorosulfonyl fluoride, is a fluorinated compound often used as a chemical building block in the production of specialty materials and fluorochemicals. It is known for its high thermal stability, chemical resistance, and low surface tension properties. PERFLUORO(2-ETHOXYETHANE)SULFONYL FLUORIDE is widely used in the production of surfactants, polymers, and as a processing aid in the manufacturing of electronics and other industrial applications. It is also used in the production of heat transfer fluids and lubricants due to its high resistance to temperature and harsh chemical environments. However, it is important to handle this chemical with care as it can be toxic if inhaled or ingested and can cause skin and eye irritation.
Check Digit Verification of cas no
The CAS Registry Mumber 67990-78-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,9,9 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 67990-78:
(7*6)+(6*7)+(5*9)+(4*9)+(3*0)+(2*7)+(1*8)=187
187 % 10 = 7
So 67990-78-7 is a valid CAS Registry Number.
