520-78-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 520-78-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,2 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 520-78:
(5*5)+(4*2)+(3*0)+(2*7)+(1*8)=55
55 % 10 = 5
So 520-78-5 is a valid CAS Registry Number.

Synthesis and DABCO-induced demethylation of 3-cyano-4-methoxy-2-pyridone derivatives

Li, Jing,Tan, Hong-Ru,An, Yu-Long,Shao, Zhi-Yu,Zhao, Sheng-Yin

, p. 486 - 496 (2020)

An efficient method for synthesis and demethylation of 3-cyano-4-methoxy-2-pyridone derivatives has been developed. DABCO-induced demethylation can lead to 3-cyano-4-hydroxy-2-pyridones in DMF at 90°C with high yield. The protocol is applicable for the synthesis of 3-cyano-4-hydroxy-2-pyridone derivatives. The method is simple, efficient, and practical.
