4-Cyanato-azobenzol, also known as 4-cyanophenylazobenzene, is an organic compound with the chemical formula C13H8N2. It is a derivative of azobenzene, featuring a cyano group (-CN) attached to the para position of one of the benzene rings. This yellow crystalline solid is widely used in the synthesis of various dyes, pigments, and other organic compounds. 4-Cyanato-azobenzol is known for its photoisomerization properties, which make it a potential candidate for applications in molecular switches and optical data storage. It is also used as an intermediate in the production of pharmaceuticals and agrochemicals. Due to its reactivity, it is essential to handle 4-cyanato-azobenzol with care, following proper safety protocols.
The CAS Registry Mumber 1601-56-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,0 and 1 respectively; the second part has 2 digits, 5 and 6 respectively. Calculate Digit Verification of CAS Registry Number 1601-56: (6*1)+(5*6)+(4*0)+(3*1)+(2*5)+(1*6)=55 55 % 10 = 5 So 1601-56-5 is a valid CAS Registry Number.
