Benzyloxycarbonylcarbazide, also known as Z-carbazide, is a chemical compound with the molecular formula C9H10N2O3. It is a derivative of carbazic acid, where the carboxylic acid group is protected by a benzyloxycarbonyl (Z) group. This protection is crucial in peptide synthesis, as it prevents unwanted side reactions involving the carboxylic acid group. Z-carbazide is a white crystalline solid that is soluble in organic solvents. It is used as a reagent in the synthesis of peptides and other organic compounds, where the Z group can be selectively removed under mild conditions to reveal the free carboxylic acid, facilitating further reactions. The compound is also known for its use in the detection of nitrites, where it forms a purple complex upon reaction, a method that is utilized in food analysis and other chemical testing applications.

Check Digit Verification of cas no

The CAS Registry Mumber 3992-29-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,9 and 2 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3992-29:
(6*3)+(5*9)+(4*9)+(3*2)+(2*2)+(1*9)=118
118 % 10 = 8
So 3992-29-8 is a valid CAS Registry Number.
