176300-99-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 176300-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,3,0 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 176300-99:
(8*1)+(7*7)+(6*6)+(5*3)+(4*0)+(3*0)+(2*9)+(1*9)=135
135 % 10 = 5
So 176300-99-5 is a valid CAS Registry Number.

Alkoxide attack on coordinated olefin can be reversible

Hauger, Bryan E.,Huffman, John C.,Caulton, Kenneth G.

, p. 1856 - 1864 (1996)

Alkoxide (MeO-, EtO-, iPrO-) attack occurs at the coordinated olefin of Ir(Tripod)(COD) (Tripod = MeC(CH2PPh2)3, COD = 1,5-cyclooctadiene) in CH2Cl2 to give Ir(Tripod)(2-alkoxycyclooct-5-en-1-yl), primarily as the exo isomer. These products slowly eliminate alcohol to give Ir(Tripod)((1,2-η2)-6-σ-cycloocta-1,4-dienyl), which is the only product detected when the alkoxide is tBuO-. Addition of excess methanol to exo-Ir(Tripod)(2-methoxycyclooct-5-en-1-yl) abstracts MeO- (i.e., heterolytic O-C bond cleavage), and thus a hydrogen-bonding solvent reverses the nucleophilic attack on coordinated olefin. Alkoxide (MeO-, iPrO-, tBuO- and 2-BuO-) addition occurs at an olefinic carbon of Rh(Tripod)(NBD)+ (NBD = norbornadiene) to give Rh(Tripod)(2-alkoxynorborn-4-en-1-yl). The crystal structure of the exo/ methoxy example has been determined. While this product cannot unimolecularly eliminate alcohol, attempts to protonate the norbornyl ether in the presence or absence of added NBD were not successful. Here again, acid abstracts RO- from the ligand ether.
