118097-61-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 118097-61-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,0,9 and 7 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 118097-61:
(8*1)+(7*1)+(6*8)+(5*0)+(4*9)+(3*7)+(2*6)+(1*1)=133
133 % 10 = 3
So 118097-61-3 is a valid CAS Registry Number.

Nickel-catalyzed 1,4-addition of trialkylboranes to α,β- unsaturated esters: Dramatic enhancement by addition of methanol

Hirano, Koji,Yorimitsu, Hideki,Oshima, Koichiro

, p. 1541 - 1544 (2008/02/02)

Equation presented Nickel catalyst systems for 1,4-addition of trialkylboranes to α,β-unsaturated esters have been developed. Addition of methanol was found to be essential for the alkylation reaction with 9-alkyl-9-BBNs.

CHLORO- AND IODOTRIMETHYLSILANE-ACTIVATED ADDITIONS OF ORGANOCOPPER COMPOUNDS TO ENONES AND ENOATES

Bergdahl, Mikael,Lindstedt, Eva-Lotte,Nilsson, Martin,Olsson, Thomas

, p. 2055 - 2062 (2007/10/02)

Organocopper compounds add to enones and enoates in the presence of chloromethylsilane in ether giving the conjugate adducts in preparatively usefu yields via the silyl enol ethers.Presence of lithium iodide is important and excess of chlorotrimethylsilane accelerates the reactions.The combination of organocopper compound, iodotrimethylsilane and dimethyl sulfide gave faster reactions and very high yields, particularly in dichloromethane, where the reaction mixtures gradually became homogeneous.
