86838-43-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 86838-43-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,8,3 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 86838-43:
(7*8)+(6*6)+(5*8)+(4*3)+(3*8)+(2*4)+(1*3)=179
179 % 10 = 9
So 86838-43-9 is a valid CAS Registry Number.

Enantioselective synthesis of α-benzyloxy-ω-alkenals: application to the synthesis of (+)-exo-brevicomin, (+)-iso-exo-brevicomin, and (-)-isolaurepan

Prasad, Kavirayani R.,Anbarasan, Pazhamalai

, p. 1419 - 1427 (2008/02/11)

The enantioselective synthesis of α-benzyloxy aldehydes containing a terminal alkene was carried out from chiral pool l-(+)-tartaric acid by employing the stereoselective reduction of a 1,4-diketone as the key step. The synthetic utility of these aldehyde

Synthesis of (+)-endo- and (+)-exo-brevicomin viaenzyme-mediated hydrolysis of an enol ester

Matsumoto, Kazutsugu,Suzuki, Natsuko,Ohta, Hiromiehi

, p. 7163 - 7166 (2007/10/02)

Optically pure (+)-endo- and (+)-exo-brevicomin have been synthesized in short steps starting from α-hydroxy ketone derivative, (R)-4-benzyloxy-8-nonen-3-one (3), which was prepared via enzymatic hydrolysis of racemic enol ester 4.
