Acetaldehyde, also known as ethanal, is a colorless, flammable, and volatile liquid with a pungent odor. It is an organic compound with the chemical formula CH3CHO, consisting of a methyl group (CH3) and an aldehyde group (CHO). Acetaldehyde is an important industrial chemical, used in the production of various products such as acetic acid, perfumes, and pharmaceuticals. Methylphenylhydrazone is a derivative of acetaldehyde, formed by the reaction of acetaldehyde with methylphenylhydrazine. Acetaldehyde, methylphenylhydrazone is used as a reagent in chemical analysis, particularly for the detection and determination of aldehydes. Methylphenylhydrazone is a yellow crystalline solid, and its formation is indicative of the presence of aldehydes in a sample.

Check Digit Verification of cas no

The CAS Registry Mumber 7423-16-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,2 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7423-16:
(6*7)+(5*4)+(4*2)+(3*3)+(2*1)+(1*6)=87
87 % 10 = 7
So 7423-16-7 is a valid CAS Registry Number.
