Check Digit Verification of cas no
The CAS Registry Mumber 87853-70-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,8,5 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 87853-70:
(7*8)+(6*7)+(5*8)+(4*5)+(3*3)+(2*7)+(1*0)=181
181 % 10 = 1
So 87853-70-1 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 (2019/12/24)
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.
