639520-83-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 639520-83-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,9,5,2 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 639520-83:
(8*6)+(7*3)+(6*9)+(5*5)+(4*2)+(3*0)+(2*8)+(1*3)=175
175 % 10 = 5
So 639520-83-5 is a valid CAS Registry Number.

Acetic Acid Accelerated Visible-Light Photoredox Catalyzed N-Demethylation of N,N-Dimethylaminophenyl Derivatives

Wu, Guolin,Li, Yazhen,Yu, Xuemei,Gao, Yu,Chen, Haijun

supporting information, p. 687 - 692 (2017/02/23)

N,N-Dimethylaminophenyl moiety is a common fragment in medicinal chemistry as several pharmaceuticals bearing this privileged motif are on the market and under clinical evaluation. Oxidative N-demethylation is generally regarded as the major metabolic pathway. However, pharmacokinetics, metabolites studies as well as the further structural modification are precluded by the impracticality of chemical synthesis. Here we report that acetic acid can significantly accelerate visible-light photoredox catalyzed N-demethylation of N,N-dimethylaminophenyl derivatives. This approach is easy for large scale reaction and even for potential industrial manufacture. (Figure presented.).
