β,β-Dichlor-α-phenyl-acrolein-semicarbazon, also known as DCP-A, is a chemical compound with the molecular formula C9H8Cl2N2. It is derived from the parent compound acrolein, which is an unsaturated aldehyde. DCP-A is characterized by the presence of two chlorine atoms attached to the beta carbon of the acrolein molecule and a semicarbazone group attached to the alpha carbon. This semicarbazone group is formed by the reaction of acrolein with semicarbazide, a derivative of hydrazine. DCP-A is an important intermediate in the synthesis of various pharmaceuticals and agrochemicals due to its reactive nature and the ability to form a wide range of derivatives. It is also known for its potential applications in the development of dyes and pigments. The compound is typically synthesized through a series of chemical reactions and is handled with care due to its potential reactivity and toxicity.

Check Digit Verification of cas no

The CAS Registry Mumber 19307-81-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,3,0 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19307-81:
(7*1)+(6*9)+(5*3)+(4*0)+(3*7)+(2*8)+(1*1)=114
114 % 10 = 4
So 19307-81-4 is a valid CAS Registry Number.
