N,N-diethylamino-P,P-dimethylphosphine, also known as DEDP, is an organophosphorus compound with the chemical formula C6H16NP. It is a colorless liquid with a pungent odor and is soluble in organic solvents. DEDP is primarily used as a lubricant additive, particularly in the automotive industry, to improve the performance and efficiency of engines. It functions by reducing friction and wear between moving parts, thereby extending the life of engine components. Additionally, DEDP has been studied for its potential applications in the synthesis of other organophosphorus compounds and as a flame retardant. However, due to its toxicity and potential environmental impact, its use is subject to strict regulations and is being phased out in some regions in favor of more environmentally friendly alternatives.

Check Digit Verification of cas no

The CAS Registry Mumber 685-93-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 685-93:
(5*6)+(4*8)+(3*5)+(2*9)+(1*3)=98
98 % 10 = 8
So 685-93-8 is a valid CAS Registry Number.
