Z-Semicarbazido-(4)-essigsaeure-ethylester and Z-'Azaglycyl'-glycin-ethylester are two distinct chemical compounds. Z-Semicarbazido-(4)-essigsaeure-ethylester, also known as Z-Semicarbazide-4-ethyl acetate, is a derivative of semicarbazide with an ethyl ester group attached to the 4-position. It is used in organic synthesis and as a protecting group in peptide chemistry. Z-'Azaglycyl'-glycin-ethylester, on the other hand, is a compound that features an 'Azaglycyl' group, which is a modified glycine residue, and an ethyl ester group. Z-Semicarbazido-(4)-essigsaeure-ethylester, Z-'Azaglycyl'-glycin-ethylester is also utilized in the synthesis of peptides and other biologically active molecules. Both chemicals are significant in the field of organic chemistry, particularly in the synthesis of complex molecules and the development of new pharmaceuticals.

4046-55-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4046-55-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,4 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4046-55:
(6*4)+(5*0)+(4*4)+(3*6)+(2*5)+(1*5)=73
73 % 10 = 3
So 4046-55-3 is a valid CAS Registry Number.
