19538-71-7 Usage

Uses

Used in Pharmaceutical Industry:
N-ACETYL-S-BENZYL-DL-CYSTEINE is used as a key intermediate in the synthesis of aryl benzamides, which are known as HIV protease inhibitors. These inhibitors play a crucial role in the development of antiretroviral drugs, as they help in the suppression of the HIV virus by blocking the activity of the HIV protease enzyme, thereby preventing the maturation of viral particles.

Check Digit Verification of cas no

The CAS Registry Mumber 19538-71-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,5,3 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19538-71:
(7*1)+(6*9)+(5*5)+(4*3)+(3*8)+(2*7)+(1*1)=137
137 % 10 = 7
So 19538-71-7 is a valid CAS Registry Number.

Formation of Thiocarbonyl Compounds in the Reaction of Ebselen Oxide with Thiols

Glass, Richard S.,Farooqui, Firdous,Sabahi, Mahmood,Ehler, Kenneth W.

, p. 1092 - 1097 (2007/10/02)

Reaction of α-toluenethiol with Ebselen oxide, 2, affords dibenzyl disulfide and seleno sulfide 5, R = PhCH2.In the course of this reaction, thiobenzaldehyde is formed and can be trapped with cyclopentadiene in 90percent yield.Reaction of 2-propene-1-thiol with 2 afforded thioacrolein dimer in 69percent yield and seleno sulfide 5, R = CH2-CH=CH2.Trapping, stereochemical, and isotopic exchange studies were used to determine if in the reaction of 2 with 1-heptanethiol, cyclohexanethiol, and N-acetyl-D,L-cysteine thiocarbonyl compounds heptanethial, cyclohexanethione, and 2-acetamino-3-thioxopropanoic acid (α-thioformyl-N-acetylglycine), respectively, are also formed.These studies showed that free thiocarbonyl compounds are not formed in these reactions.
