α-Keto-valeriansaeure-methylester-2.4-dinitro-phenylhydrazon, also known as α-keto-isovaleric acid methyl ester 2,4-dinitrophenylhydrazone, is a chemical compound derived from α-keto-isovaleric acid. It is formed by the reaction of α-keto-isovaleric acid methyl ester with 2,4-dinitrophenylhydrazine, resulting in the formation of a hydrazone derivative. α-Keto-valeriansaeure-methylester-2.4-dinitro-phenylhydrazon is often used in organic chemistry as a reagent for the detection and identification of carbonyl compounds, such as ketones and aldehydes, due to its distinct color change upon reaction. The 2,4-dinitrophenylhydrazone group serves as a chromophore, providing a visible indication of the presence of the carbonyl group in the molecule.

Check Digit Verification of cas no

The CAS Registry Mumber 6395-81-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,9 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6395-81:
(6*6)+(5*3)+(4*9)+(3*5)+(2*8)+(1*1)=119
119 % 10 = 9
So 6395-81-9 is a valid CAS Registry Number.
