91879-31-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91879-31-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,7 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 91879-31:
(7*9)+(6*1)+(5*8)+(4*7)+(3*9)+(2*3)+(1*1)=171
171 % 10 = 1
So 91879-31-1 is a valid CAS Registry Number.

Enantioselective Synthesis and Biological Activity of (3S,4R)- and (3S,4S)-3-Hydroxy-4-hydroxymethyl-4-butanolides in Relation to PGE2

Miranda, Pedro O.,Estévez, Francisco,Quintana, José,Garcia, Candelaria I.,Brouard, Ignacio,Padrón, Juan I.,Pivel, Juan P.,Bermejo, Jaime

, p. 292 - 295 (2007/10/03)

Compounds 9 and 13 were synthesized, and their structures and stereochemistry were elucidated by spectroscopic methods. In competition binding experiments, specific [3H]-PGE2 binding was significantly displaced by compound 9 and, to a lesser extent, by 13, in a dose-dependent manner. The biological properties of compound 9 were studied on HL-60 cells, and several effects were found related to those of PGE 2. Compound 9 increases c-fos mRNA level as does PGE2 and antagonizes TPA-induced terminal differentiation.
