947-52-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 947-52-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,4 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 947-52:
(5*9)+(4*4)+(3*7)+(2*5)+(1*2)=94
94 % 10 = 4
So 947-52-4 is a valid CAS Registry Number.

Total Synthesis and Structural Revision of Chaetoviridins A

Makrerougras, Mehdi,Coffinier, Romain,Oger, Samuel,Chevalier, Arnaud,Sabot, Cyrille,Franck, Xavier

, p. 4146 - 4149 (2017)

The first synthesis of the proposed structures of chaetoviridins A 1-4 has been achieved in 10 steps by controlling the syn- or anti-aldol side chain. The angular lactone has been regioselectively introduced by condensation of a chiral dioxin-4-one to cazisochromene. Comparison of the NMR and circular dichroism data of the synthesized and reported natural products led to the complete reassignment and renaming of the chaetoviridins.

Chemical constituents of the lichen, Candelaria concolor: A complete NMR and chemical degradative investigation

Dias, Daniel A.,Urban, Sylvia

scheme or table, p. 925 - 939 (2010/08/19)

A detailed chemical and spectroscopic investigation of the terrestrial lichen Candelaria concolor has yielded several lichenic metabolites belonging to the pulvinic acid series, as well as several depside derivatives including pulvinic dilactone (1), vulpinic acid (4) and calycin (5). The chemical transformation of 1 to pulvinic acid (3) is reported for the first time, as is the conversion of atranorin (6) to 5-chloroatranorin (7) and then finally to 5,5'-dichloroatranorin (8) under very mild conditions. Also presented is the complete 1D and 2D NMR assignment for compounds 1, 3, 4, 5 and 8, including partial NMR chemical shift assignments for the unstable depside (7). Previously, these metabolites had only been partially assigned by NMR spectroscopy.
