371247-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 371247-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,1,2,4 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 371247-45:
(8*3)+(7*7)+(6*1)+(5*2)+(4*4)+(3*7)+(2*4)+(1*5)=139
139 % 10 = 9

Synthesis of (-)-epibatidine
Evans, David A.,Scheidt, Karl A.,Downey, C. Wade
, p. 3009 - 3012 (2007/10/03)
matrix presented The synthesis of (-)-epibatidine has been accomplished utilizing a highly exo-selective asymmetric hetero Diels-Alder reaction. The key steps employed to transform the resulting bicycle into the natural product include a fluoride-promoted fragmentation and a Hofmann rearrangement.
