89465-16-7 Usage
General Description
2,4(1H,3H)-Pyrimidinedione, 1-methyl-6-(methylamino)-, commonly known as caffeine, is a central nervous system stimulant that belongs to the xanthine alkaloid class of compounds. It is found in various beverages, including coffee, tea, and energy drinks, and is also used in pharmaceuticals and as an additive in food products. Caffeine works by blocking the action of adenosine, a neurotransmitter that promotes sleep and relaxation. This results in increased alertness, improved attention and concentration, and reduced fatigue. However, excessive consumption of caffeine can lead to adverse effects such as insomnia, anxiety, and palpitations.
Check Digit Verification of cas no
The CAS Registry Mumber 89465-16-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,4,6 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 89465-16:
(7*8)+(6*9)+(5*4)+(4*6)+(3*5)+(2*1)+(1*6)=177
177 % 10 = 7
So 89465-16-7 is a valid CAS Registry Number.

Purines XIV. [1]. Reactivity of 8-Bromo-3,9-dimethylxanthine Towards Some Nucleophilic Reagents
Youssef, Shaker,Pfleiderer, Wolfgang
, p. 949 - 954 (2007/10/03)
The reactivity of 8-bromo-3,9-dimethylxanthine (6) towards a variety of nucleophilic reagents has been investigated. Nucleophilic displacements take place easily with aliphatic mercaptans and aliphatic alcohols, whereas aliphatic amines required more severe conditions. Prolonged heating of 6 with amines causes a new type of rearrangement from 3,9- to 3,7-dimethylxanthines due to a 1,3-sigmatropic shift of the N(9)-methyl group.
