Check Digit Verification of cas no

The CAS Registry Mumber 1232140-16-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,2,1,4 and 0 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1232140-16:
(9*1)+(8*2)+(7*3)+(6*2)+(5*1)+(4*4)+(3*0)+(2*1)+(1*6)=87
87 % 10 = 7

Practical and scalable synthesis of ethyl (R)-piperidine-3-acetate

Zhu, Ying-Guang,Kan, Hong-Zhu,Jiang, Li-Qin,Hu, Wen-Hao

, p. 1137 - 1145 (2012)

A practical and scalable synthesis of ethyl (R)-piperidine-3-acetate was achieved from commercially available 3-pyridylacetic acid in 76% overall yield. The practical synthesis was demonstrated on 100-g scale. One-pot reductive N-ethylation of the pyridinium salt with acetonitrile gave an N-ethyl piperidine derivative.
