"N-(N-trityl-glycyl)-L-tyrosine ethyl ester" is a complex organic compound with the chemical formula C34H33NO4. It is a derivative of L-tyrosine, an amino acid, with an ethyl ester group attached to the carboxylic acid group and a trityl-glycyl moiety attached to the nitrogen atom. N-(N-trityl-glycyl)-L-tyrosine ethyl ester is often used in peptide synthesis as a protected amino acid, where the trityl group serves as a protecting group for the amino group, and the ethyl ester group protects the carboxylic acid group. The trityl group can be removed under acidic conditions, while the ethyl ester can be hydrolyzed to the free acid under basic conditions. N-(N-trityl-glycyl)-L-tyrosine ethyl ester plays a crucial role in the synthesis of peptides and proteins, allowing chemists to control the reactivity of the amino acid and prevent unwanted side reactions during the assembly of peptide chains.

Check Digit Verification of cas no

The CAS Registry Mumber 3561-38-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,6 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3561-38:
(6*3)+(5*5)+(4*6)+(3*1)+(2*3)+(1*8)=84
84 % 10 = 4
So 3561-38-4 is a valid CAS Registry Number.
