"Z(NO2)-Ileu-Glykolsaeure-pentamethylbenzylester" is a complex chemical compound, which can be broken down into its constituent parts for better understanding. "Z(NO2)" refers to the nitrobenzyloxycarbonyl group, a protecting group used in peptide synthesis to prevent unwanted side reactions. "Ileu" stands for isoleucine, an essential amino acid that plays a crucial role in various biological processes. "Glykolsaeure" is the German term for glycolic acid, a simple alpha-hydroxy acid with exfoliating and moisturizing properties. Lastly, "pentamethylbenzylester" denotes the pentamethylbenzyl ester group, which is a bulky protecting group used in organic synthesis to shield certain functional groups. Overall, Z(NO2)-Ileu-Glykolsaeure-pentamethylbenzylester is a derivative of isoleucine with a nitrobenzyloxycarbonyl group, glycolic acid, and a pentamethylbenzyl ester group, indicating its potential use in peptide synthesis and chemical research.
The CAS Registry Mumber 19405-40-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,0 and 5 respectively; the second part has 2 digits, 4 and 0 respectively. Calculate Digit Verification of CAS Registry Number 19405-40: (7*1)+(6*9)+(5*4)+(4*0)+(3*5)+(2*4)+(1*0)=104 104 % 10 = 4 So 19405-40-4 is a valid CAS Registry Number.
