Check Digit Verification of cas no

The CAS Registry Mumber 39257-91-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,2,5 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 39257-91:
(7*3)+(6*9)+(5*2)+(4*5)+(3*7)+(2*9)+(1*1)=145
145 % 10 = 5
So 39257-91-5 is a valid CAS Registry Number.

STUDIES DIRECTED TOWARDS THE TOTAL SYNTHESIS OF DICYCLOPENTACYCLOOCTANE TERPENOIDS.

De Gregori, A.,Jommi, G.,Sisti, M.,Gariboldi, P.,Merati, F.

, p. 2549 - 2568 (1988)

A general strategy for the synthesis of dicyclopentacyclooctane terpenoids is reported.Compound 1 was synthesized from 3-methoxycarbonyl-2-cyclopentenone; its photocycloaddition led to four diastereoisomeric photoadducts whose structure were determined by X-ray analysis, 1H-NMR data and chemical transformations.

Solid-phase synthesis of thermolytic DNA oligonucleotides functionalized with a single 4-hydroxy-1-butyl or 4-phosphato-/thiophosphato-1-butyl thiophosphate protecting group

Grajkowski, Andrzej,Ausin, Cristina,Kauffman, Jon S.,Snyder, John,Hess, Sonja,Lloyd, John R.,Beaucage, Serge L.

, p. 805 - 815 (2007/10/03)

(Chemical Equation Presented) Several thermolytic CpG-containing DNA oligonucleotides analogous to 1 have been synthesized to serve as potential immunotherapeutic oligonucleotide prodrug formulations for the treatment of infectious diseases in animal models. Specifically, the CpG motif (GACGTT) of each DNA oligonucleotide has been functionalized with either the thermolabile 4-hydroxy-1-butyl or the 4-phosphato-/thiophosphato-1-butyl thiophosphate protecting group. This functionalization was achieved through incorporation of activated deoxyribonucleoside phosphoramidite 8b into the oligonucleotide chain during solid-phase synthesis and, optionally, through subsequent phosphorylation effected by phosphoramidite 9. Complete conversion of CpG ODNs hbu1555, psb1555, and pob1555 to CpG ODN 1555 (homologous to 2) occurred under elevated temperature conditions, thereby validating the function of these diastereomeric oligonucleotides as prodrugs in vitro. Noteworthy is the significant increase in solubility of CpG ODN psb1555 and CpG pob1555 in water when compared to that of neutral CpG ODN fma1555 (homologous to 1).
