3-(4-Chlorphenoxy)-crotonsaeureethylester, also known as ethyl 3-(4-chlorophenoxy)acrylate, is an organic compound with the chemical formula C11H11ClO3. It is a colorless to pale yellow liquid with a molecular weight of 224.66 g/mol. 3-<4-Chlorphenoxy>-crotonsaeureethylester is primarily used as an intermediate in the synthesis of various agrochemicals, particularly herbicides. It is characterized by its reactivity due to the presence of the electron-rich double bond, which can undergo addition reactions with electrophiles. The 4-chlorophenoxy group attached to the crotonic acid ester moiety plays a crucial role in the biological activity of the final products. Handling and storage of this chemical require appropriate safety measures due to its potential irritant and toxic properties.

Check Digit Verification of cas no

The CAS Registry Mumber 1212-27-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,1 and 2 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1212-27:
(6*1)+(5*2)+(4*1)+(3*2)+(2*2)+(1*7)=37
37 % 10 = 7
So 1212-27-7 is a valid CAS Registry Number.
