Check Digit Verification of cas no
The CAS Registry Mumber 19740-86-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,7,4 and 0 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 19740-86:
(7*1)+(6*9)+(5*7)+(4*4)+(3*0)+(2*8)+(1*6)=134
134 % 10 = 4
So 19740-86-4 is a valid CAS Registry Number.

Transannular O -heterocyclization: A useful tool for the total synthesis of Murisolin and 16,19- cis -Murisolin

Transannular O-heterocyclization is applied as a key step in a total synthesis. This highly stereoselective and metal-free transformation introduces four stereocenters in one step. It was chosen to be the pivotal step in the synthesis of Murisolin and 16,19-cis-Murisolin, two annonaceous acetogenins. The efficiency of this synthesis is further illustrated by a stereodivergent late-stage separation of both synthetic routes.
Selectivity of Candida rugosa lipase in simultaneous separation of skeletal isomers, desymmetrization, and kinetic racemate cleavage of 9-oxabicyclononanediols

The diols 2 and 3, available in one step from cycloocta-1,5-diene, are selectively acetylated at the (R)-centers using Candida rugosa lipase to give the corresponding enantiopure compounds. In contrast, the (S,S)-enantiomer of 11 is transformed under iden
