1258-19-1 Usage
General Description
2,2,6,6-tetraphenylheptanedinitrile, also known as tetrakis(phenyl)methane dinitrile, is a chemical compound with the molecular formula C30H22N2. It is a white to light yellow powder that is insoluble in water but soluble in organic solvents. 2,2,6,6-tetraphenylheptanedinitrile is primarily used as a fluorescent whitening agent in the manufacture of plastics, fibers, and other materials to enhance their appearance by absorbing ultraviolet light and emitting blue light. It is also used as a building block in the synthesis of complex organic molecules and as a stabilizer in the production of polymers. 2,2,6,6-tetraphenylheptanedinitrile is considered to be relatively safe, with low acute toxicity, but should be handled with care and according to appropriate safety measures.
Check Digit Verification of cas no
The CAS Registry Mumber 1258-19-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,5 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1258-19:
(6*1)+(5*2)+(4*5)+(3*8)+(2*1)+(1*9)=71
71 % 10 = 1
So 1258-19-1 is a valid CAS Registry Number.

Hydride Reduction by a Sodium Hydride-Iodide Composite

Sodium hydride (NaH) is widely used as a Br?nsted base in chemical synthesis and reacts with various Br?nsted acids, whereas it rarely behaves as a reducing reagent through delivery of the hydride to polar π electrophiles. This study presents a series of reduction reactions of nitriles, amides, and imines as enabled by NaH in the presence of LiI or NaI. This remarkably simple protocol endows NaH with unprecedented and unique hydride-donor chemical reactivity.
