155897-14-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 155897-14-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,8,9 and 7 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 155897-14:
(8*1)+(7*5)+(6*5)+(5*8)+(4*9)+(3*7)+(2*1)+(1*4)=176
176 % 10 = 6
So 155897-14-6 is a valid CAS Registry Number.

Divergence en route to nonclassical annonaceous acetogenins. Synthesis of pyranicin and pyragonicin

Strand, Daniel,Norrby, Per-Ola,Rein, Tobias

, p. 1879 - 1891 (2007/10/03)

Syntheses of the nonclassical annonaceous acetogenins, pyranicin, and pyragonicin from common late-stage intermediates are presented. The construction of key elements relies on asymmetric HWE reactions, including the desymmetrization of a meso-dialdehyde

Parallel kinetic resolution of racemic aldehydes by use of asymmetric Horner-Wadsworth-Emmons reactions

Pedersen, Torben M.,Jensen, Jakob F.,Humble, Rikke E.,Rein, Tobias,Tanner, David,Bodmann, Kerstin,Reiser, Oliver

, p. 535 - 538 (2007/10/03)

(Formula presented) A racemic aldehyde can undergo parallel kinetic resolution (PKR) by simultaneous reaction with two different chiral phosphonates, differing either in the structure of the chiral auxiliary or in the structure of the phosphoryl group (i.
