14826-58-5 Usage
General Description
1-(2-oxoazepan-1-yl)butane-1,3-dione, also known as 2,5-dimethyl-2,5-hexanedione or diacetyl, is a chemical compound commonly used as a flavoring agent in the food industry, particularly in butter-flavored products such as microwave popcorn, margarine, and snack foods. It is also found in some e-cigarette liquids and other vaping products. Diacetyl has a creamy, buttery taste and aroma, which makes it desirable as a flavoring agent. However, it has been linked to respiratory issues and lung disease, particularly in workers who have been exposed to high levels of the chemical. In response to these health concerns, some manufacturers have started to phase out the use of diacetyl in their products.
Check Digit Verification of cas no
The CAS Registry Mumber 14826-58-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,8,2 and 6 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 14826-58:
(7*1)+(6*4)+(5*8)+(4*2)+(3*6)+(2*5)+(1*8)=115
115 % 10 = 5
So 14826-58-5 is a valid CAS Registry Number.

Catalytic asymmetric [3+2] cycloaddition of isomünchnones with methyleneindolinones
Wang, Kaixuan,Xu, Chaoran,Hu, Xinyue,Zhou, Yuqiao,Lin, Lili,Feng, Xiaoming
supporting information, p. 8917 - 8920 (2021/09/10)
An efficient enantioselective [3+2] cycloaddition of isomünchnones with methyleneindolinones that are generated by anin situintramolecular addition of the carbonyl group to rhodium carbenes is realized with a chiralN,N′-dioxide/Zn(ii) complex as a Lewis acid. A series of chiral oxa-bridged 3-spiropiperidines are obtained in high yields with excellent dr and excellent ee values.
