General Description
3,5-diiodophenol, also known as 3,5-diiodo-1-hydroxybenzene, is a chemical compound with the molecular formula C6H4I2O. It is a derivative of phenol, featuring two iodine atoms attached to the 3 and 5 positions of the benzene ring. 3,5-diiodophenol is commonly used as a reagent in organic synthesis, particularly in the preparation of various pharmaceuticals and dyes. It is also utilized as a precursor to other iodinated compounds and as a building block in the production of specialty chemicals. Due to its strong iodine content, 3,5-diiodophenol has potential applications in radiopharmaceuticals and medical imaging. However, it is important to handle this compound with caution, as iodine-containing chemicals can be toxic and should be used in a well-ventilated environment with appropriate personal protective equipment.
Check Digit Verification of cas no
The CAS Registry Mumber 20981-79-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,9,8 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20981-79:
(7*2)+(6*0)+(5*9)+(4*8)+(3*1)+(2*7)+(1*9)=117
117 % 10 = 7
So 20981-79-7 is a valid CAS Registry Number.
