66224-70-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 66224-70-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,2,2 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 66224-70:
(7*6)+(6*6)+(5*2)+(4*2)+(3*4)+(2*7)+(1*0)=122
122 % 10 = 2
So 66224-70-2 is a valid CAS Registry Number.

Synthesis of unstable carbides Ag2C2n (n = 3, 4) and characterization via crystallographic analysis of their double salts with silver(I) trifluoroacetate

Hau, Sam C. K.,Mak, Thomas C. W.

, p. 902 - 905 (2014)

Two new silver(I) carbides, Ag2C6 and Ag 2C8, have been synthesized, and single-crystal X-ray analysis of their crystalline silver(I) trifluoroacetate complexes, Ag 2C6·8AgCF3CO2·6H 2O, 4(Ag2C6)·16AgCF3CO 2·14.5DMSO, and 2.5(Ag2C8) ·10AgCF3CO2·10DMSO, provides detailed information on the influence of ligand disposition and orientation of the all-carbon anionic ligands in the construction of multidimensional supramolecular structures, which are consolidated by argentophilic and weak inter-/intramolecular interactions.

Synthesis of trimethylsilylpropynoyl chloride

Medvedeva,Andreev,Safronova,Afonin

, p. 1463 - 1466 (2005)

Trimethylsilylpropynoic acid reacts with thionyl chloride to give a mixture of trimethylsilylpropynoyl chloride and 3-chloro-3-trimethylsilyl-2-propenoyl chloride whose ratio depends on the reaction conditions (temperature, reactant ratio). Dimethylformamide almost does not catalyze the reaction. Treatment of trimethylsilylpropynoic acid with oxalyl chloride in the presence of 0.04 equiv of DMF at room temperature ensures selective formation of trimethylsilylpropynoyl chloride (yield 80%).

One-pot synthesis of 3-(trimethylsilyl)propynamides

Medvedeva,Andreev,Safronova

, p. 1466 - 1470 (2010)

A highly efficient one-pot procedure was developed for the synthesis of 3-trimethylsilylpropynamides by acylation of amines with trimethylsilylpropynoyl chloride generated in situ. Selective N-acylation and N,O-bis-acylation of -amino alcohols with format

Phosphorescent proteins for bio-imaging and site selective bio-conjugation of peptides and proteins with luminescent cyclometalated iridium(iii) complexes

Shiu, Hoi-Yan,Chong, Hiu-Chi,Leung, Yun-Chung,Zou, Taotao,Che, Chi-Ming

, p. 4375 - 4378 (2014)

A new bio-conjugation reaction for site selective modification of proteins and peptides with phosphorescent iridium(iii) complexes has been developed; the Ir(iii)-modified proteins and peptides display long emission lifetimes and large Stoke shifts that can be used for bio-imaging studies.
