"N-(N-benzyloxycarbonyl-glycyl)-N,N'-dicyclohexyl-urea" is a complex organic compound with the molecular formula C21H30N2O4. It is a derivative of urea, featuring a benzyloxycarbonyl-glycyl group attached to the nitrogen atom, and two cyclohexyl groups connected to the other nitrogen atom. N-(N-benzyloxycarbonyl-glycyl)-N,N'-dicyclohexyl-urea is often used in peptide synthesis as a protecting group for the amino group, which prevents unwanted side reactions during the formation of peptide bonds. The benzyl group can be removed under acidic conditions, allowing for the subsequent steps in peptide synthesis. The dicyclohexyl groups provide steric hindrance, which can influence the reactivity and selectivity of the compound in chemical reactions.
The CAS Registry Mumber 1738-93-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,3 and 8 respectively; the second part has 2 digits, 9 and 3 respectively. Calculate Digit Verification of CAS Registry Number 1738-93: (6*1)+(5*7)+(4*3)+(3*8)+(2*9)+(1*3)=98 98 % 10 = 8 So 1738-93-8 is a valid CAS Registry Number.
