219143-76-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 219143-76-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,1,4 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 219143-76:
(8*2)+(7*1)+(6*9)+(5*1)+(4*4)+(3*3)+(2*7)+(1*6)=127
127 % 10 = 7
So 219143-76-7 is a valid CAS Registry Number.

A concise synthesis of (-)-mesembrine

Dalko, Peter I.,Brun, Virginie,Langlois, Yves

, p. 8979 - 8982 (2007/10/03)

(-)-Mesembrine 11 was synthesized in 7 steps, in 19.4% overall yield and with ee>95%. The key step of the sequence is a stereoselective alkylation reaction of dianion derived from C2 symmetric imidazolines allowing efficient formation of quaternary benzylic center. Chiral auxiliaries derived from (S,S)-1,2-diamino-1,2-diphenylethane 1a and (S,S)-1,2-diaminocyclohexane 1b were compared. This synthesis provided unambiguous correlation of the newly formed stereocenter.
