2-Pentanone, 1,1,1-trichloro-4-hydroxy-4-[(phenylmethyl)amino]-, also known as chloroprocaine, is a chemical compound with the molecular formula C13H16Cl3NO2. It is a local anesthetic agent used in medical procedures, particularly in dentistry and ophthalmology, due to its fast onset and short duration of action. Chloroprocaine is synthesized by reacting 2-pentanone with chloroform and ammonia, followed by the addition of benzylamine. The compound is characterized by its three chlorine atoms, a hydroxyl group, and a phenylmethylamino group, which contribute to its anesthetic properties. It is a colorless to pale yellow liquid with a molecular weight of 340.63 g/mol. Chloroprocaine is known for its low toxicity and is metabolized rapidly in the body, making it a preferred choice for certain medical applications.

The CAS Registry Mumber 839-38-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,3 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 839-38:
(5*8)+(4*3)+(3*9)+(2*3)+(1*8)=93
93 % 10 = 3
So 839-38-3 is a valid CAS Registry Number.
