(4-phenylazo-phenyl)-carbamic acid-(4-chloro-but-2-ynyl ester) is a complex organic compound with the molecular formula C21H15ClN2O3. It is characterized by a phenylazo group attached to a phenyl ring, which is further connected to a carbamic acid moiety. The carbamic acid is esterified with a 4-chloro-but-2-ynyl group, which introduces a halogenated alkyne functionality. This molecule is of interest in the field of organic chemistry, particularly in the synthesis of dyes and pigments, due to its unique structure and potential reactivity. The presence of the phenylazo group and the chlorinated alkyne group suggests that it may have applications in the development of compounds with specific color properties or as intermediates in the synthesis of more complex molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 4836-74-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,3 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4836-74:
(6*4)+(5*8)+(4*3)+(3*6)+(2*7)+(1*4)=112
112 % 10 = 2
So 4836-74-2 is a valid CAS Registry Number.
