211426-27-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 211426-27-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,4,2 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 211426-27:
(8*2)+(7*1)+(6*1)+(5*4)+(4*2)+(3*6)+(2*2)+(1*7)=86
86 % 10 = 6
So 211426-27-6 is a valid CAS Registry Number.

Formal synthesis of natural epibatidine and of its enantiomer: Use of radical cyclization in an enantiospecific route
Clive, Derrick L. J.,Yeh, Vince S. C.
, p. 4789 - 4792 (2007/10/03)
(S)-Pyroglutamic acid was converted into the (phenylthio)acetylene 14, which undergoes radical cyclization to the 7-azabicyclo[2.2.1]heptane 15. Ozonolysis then affords ketone 4, a synthetic precursor of (-)-epibatidine.
