883893-69-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 883893-69-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,3,8,9 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 883893-69:
(8*8)+(7*8)+(6*3)+(5*8)+(4*9)+(3*3)+(2*6)+(1*9)=244
244 % 10 = 4
So 883893-69-4 is a valid CAS Registry Number.

Mild ruthenium-catalyzed intermolecular alkyne cyclotrimerization

Das, Sanjoy K.,Roy, Rene

, p. 4015 - 4018 (1999)

Grubbs' catalyst [(PCy3)2Cl2Ru=CHPh, 7] was shown for the first time to be an effective catalyst for the mild intermolecular cyclotrimerization of terminal alkynes (1-6). The reaction is general and the isomeric trisubstit

Iron-catalyzed regioselective cyclotrimerization of alkynes to benzenes

Gawali, Suhas Shahaji,Gunanathan, Chidambaram

, p. 139 - 149 (2019/01/03)

We report the synthesis and characterization of simple di(aminomethyl)pyridine ligated iron-pincer complexes, which catalyzed the regioselective [2+2+2] cyclotrimerization of terminal aryl and alkyl alkynes to provide the 1,2,4-trisubstituted benzene molecules. Interestingly, internal alkynes also exhibited similar cyclization and resulted in hexa-substituted benzene compounds. Increased steric bulk on pincer ligands diminished the selectivity for cycloaddition. Cyclotrimerization reactions proceeded at room temperature upon activation of catalyst by a Grignard reagent. EPR studies indicated thermally induced spin crossover effect in catalyst.

Remarkable drug-release enhancement with an elimination-based AB3 self-immolative dendritic amplifier

Sagi, Amit,Segal, Ehud,Satchi-Fainaro, Ronit,Shabat, Doron

, p. 3720 - 3727 (2008/02/07)

Self-immolative dendritic prodrugs, activated through a single catalytic reaction by a specific enzyme, could offer significant advantages in inhibition of tumor growth relative to monomeric prodrug, especially if the targeted or secreted enzyme exists at
