Check Digit Verification of cas no

The CAS Registry Mumber 91142-86-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,1,4 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 91142-86:
(7*9)+(6*1)+(5*1)+(4*4)+(3*2)+(2*8)+(1*6)=118
118 % 10 = 8
So 91142-86-8 is a valid CAS Registry Number.

Stereoselective synthesis of 5′-hydroxyzearalenone

Avuluri, Srilatha,Bujaranipalli, Sheshurao,Das, Saibal,Yadav

, p. 3547 - 3549 (2018)

A first stereoselective total synthesis of 14-memebered β-resorcylic macrolactone 5′-hydroxyzearalenone (1) has been achieved. The key steps are Jocobsen hydrolytic kinetic resolution, Sharpless asymmetric dihydroxylation, Vilsmeier-Haack reaction, Mitsunobu esterification and ring-closing metathesis.

Catalytic asymmetric total synthesis of (S)-(-)-zearalenone, a novel lipoxygenase inhibitor

Baggelaar, Marc P.,Huang, Yange,Feringa, Ben L.,Dekker, Frank J.,Minnaard, Adriaan J.

, p. 5271 - 5274 (2013/09/02)

A catalytic asymmetric synthesis of (S)-(-)-zearalenone is reported using asymmetric allylic alkylation for the introduction of the stereocenter. (S)-(-)-Zearalenone turned out to be a novel lipoxygenase inhibitor.
