Check Digit Verification of cas no

The CAS Registry Mumber 340181-93-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,0,1,8 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 340181-93:
(8*3)+(7*4)+(6*0)+(5*1)+(4*8)+(3*1)+(2*9)+(1*3)=113
113 % 10 = 3
So 340181-93-3 is a valid CAS Registry Number.

A unified strategy to prostaglandins: chemoenzymatic total synthesis of cloprostenol, bimatoprost, PGF2α, fluprostenol, and travoprost guided by biocatalytic retrosynthesis

, p. 10362 - 10370 (2021/08/16)

Development of efficient and stereoselective synthesis of prostaglandins (PGs) is of utmost importance, owing to their valuable medicinal applications and unique chemical structures. We report here a unified synthesis of PGs cloprostenol, bimatoprost, PGF2α, fluprostenol, and travoprost from the readily available dichloro-containing bicyclic ketone6aguided by biocatalytic retrosynthesis, in 11-12 steps with 3.8-8.4% overall yields. An unprecedented Baeyer-Villiger monooxygenase (BVMO)-catalyzed stereoselective oxidation of6a(99% ee), and a ketoreductase (KRED)-catalyzed diastereoselective reduction of enones12(87?:?13 to 99?:?1 dr) were utilized in combination for the first time to set the critical stereochemical configurations under mild conditions. Another key transformation was the copper(ii)-catalyzed regioselectivep-phenylbenzoylation of the secondary alcohol of diol10(9.3?:?1 rr). This study not only provides an alternative route to the highly stereoselective synthesis of PGs, but also showcases the usefulness and great potential of biocatalysis in construction of complex molecules.
