Isonicotinsaeure-ethoxycarbonylhydrazid, also known as isonicotinoyl ethoxycarbonyl hydrazide, is a chemical compound with the molecular formula C9H12N4O3. It is a derivative of isonicotinic acid, which is a type of pyridine carboxylic acid. Isonicotinsaeure-ethoxycarbonylhydrazid is characterized by the presence of a hydrazide group attached to the isonicotinic acid structure through an ethoxycarbonyl linker. It is often used in organic synthesis and as an intermediate in the preparation of various pharmaceuticals and agrochemicals. The ethoxycarbonyl group provides a protecting function for the hydrazide, which can be removed under specific conditions to reveal the active hydrazide group for further reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 4811-93-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,1 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4811-93:
(6*4)+(5*8)+(4*1)+(3*1)+(2*9)+(1*3)=92
92 % 10 = 2
So 4811-93-2 is a valid CAS Registry Number.
