1542980-67-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1542980-67-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,4,2,9,8 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1542980-67:
(9*1)+(8*5)+(7*4)+(6*2)+(5*9)+(4*8)+(3*0)+(2*6)+(1*7)=185
185 % 10 = 5
So 1542980-67-5 is a valid CAS Registry Number.

Synthesis of (-)-epibatidine
Chiou, Wen-Hua,Chiang, Yu-Min
, p. 11444 - 11446 (2014)
An asymmetric synthesis to the dendrobatid alkaloid (-)-epibatidine has been described, featuring chiral resolution of both optically pure 7-azabicyclo[2.2.1]heptanecarboxylic acid, and subsequent transformations to (-)-epibatidine. The methodology provides a flexible access to various substituted chiral epibatidine analogues.
