19219-98-8 Usage
General Description
2,5,6-Trimethylbenzoxazole is a chemical compound with the molecular formula C10H9NO. It is a white to pale yellow solid that is commonly used as a fluorescent whitening agent in various industrial and consumer products, such as paper, plastics, and textiles. It absorbs ultraviolet light and re-emits it as visible blue light, giving these products a brighter and cleaner appearance. 2,5,6-Trimethylbenzoxazole is also used in the manufacturing of optical brightening agents, dyes, and pigments. It has low toxicity and is not considered to be a harmful substance when used in accordance with safety regulations.
Check Digit Verification of cas no
The CAS Registry Mumber 19219-98-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,2,1 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 19219-98:
(7*1)+(6*9)+(5*2)+(4*1)+(3*9)+(2*9)+(1*8)=128
128 % 10 = 8
So 19219-98-8 is a valid CAS Registry Number.

One-pot synthesis of benzoxazoles via the metal-free ortho-C-H functionalization of phenols with nitroalkanes
Aksenov, Nicolai A.,Aksenov, Alexander V.,Nadein, Oleg N.,Aksenov, Dmitrii A.,Smirnov, Alexander N.,Rubin, Michael
, p. 71620 - 71626 (2015)
PPA-activated nitroalkanes are employed in the design of a one-pot cascade transformation involving metal-free and oxidant-free direct ortho-C-H functionalization, followed by Beckman rearrangement and intramolecular cyclocondensation to produce benzoxazoles and benzobisoxazoles directly from easily available phenols.
