It is a yellow crystalline solid that is derived from diphenyl selenide, where one of the hydrogen atoms is replaced by a chlorine atom, and two nitro groups are attached to the ortho and para positions of the phenyl rings. 2'-Chlor-2.4-dinitro-diphenylselenid is characterized by its high reactivity and is used in the synthesis of various organic compounds, particularly those containing selenium. Due to its potential toxicity and reactivity, it is important to handle this chemical with care and in accordance with proper safety protocols.
The CAS Registry Mumber 1657-96-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,5 and 7 respectively; the second part has 2 digits, 9 and 6 respectively. Calculate Digit Verification of CAS Registry Number 1657-96: (6*1)+(5*6)+(4*5)+(3*7)+(2*9)+(1*6)=101 101 % 10 = 1 So 1657-96-1 is a valid CAS Registry Number.
