Check Digit Verification of cas no

The CAS Registry Mumber 153786-93-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,7,8 and 6 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 153786-93:
(8*1)+(7*5)+(6*3)+(5*7)+(4*8)+(3*6)+(2*9)+(1*3)=167
167 % 10 = 7
So 153786-93-7 is a valid CAS Registry Number.

Reinvestigating the acyl cyclization to the precursor of diptoindonesin G

Li, Nan-Sheng,Greene, Geoffrey L.

, (2021/03/29)

We reinvestigated the synthesis of the precursor of diptoindonesin G (2) by the intramolecular acyl cyclization of compound 1 or compound 3 in the presence of trifluoroacetic anhydride (TFAA) [1,2]. Although the reaction of 3 with TFAA generated 2 smoothl

Taxane synthesis through intramolecular pinacol coupling at C-1-C-2. Construction and oxidative transformations of a C-aromatic taxane diene

Swindell, Charles S.,Chander, Madhavi C.,Heerding, Julia M.,Klimko, Peter G.,Rahman, Leera T.,Roman, J. Venkat,Venkataraman, Hemalatha

, p. 1101 - 1108 (2007/10/03)

A ten-linear-step construction of C-aromatic taxane diene 14 from ethylisopropyl ketone, acryloyl chloride, and commercially available 8 is reported. This sequence concludes with an intramolecular pinacol coupling carried out on 13. 14 is oxidized by m-ch
