55001-04-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 55001-04-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,0,0 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 55001-04:
(7*5)+(6*5)+(5*0)+(4*0)+(3*1)+(2*0)+(1*4)=72
72 % 10 = 2
So 55001-04-2 is a valid CAS Registry Number.

Enantioselective halogenative semi-pinacol rearrangement: A stereodivergent reaction on a racemic mixture

Romanov-Michailidis, Fedor,Pupier, Marion,Gune, Laure,Alexakis, Alexandre

, p. 13461 - 13464 (2015/02/19)

An efficient, quantitative deracemization strategy for optically inactive allylic cycloalkanols has been achieved using the biphasic halogenative semi-pinacol reaction protocol. The resultant β-halo spiroketones, containing three contiguous stereogenic ce

Lipase catalyzed acylation of primary alcohols with remotely located stereogenic centres: the resolution of (±)-4,4-dimethyl-3-phenyl-1-pentanol

Sabbani, Sunil,Hedenstroem, Erik,Andersson, Jimmy

, p. 1712 - 1720 (2008/02/11)

Enantioselective acylation of some (±)-3-alkyl-3-phenyl-1-propanols was performed with enzymes as catalysts. Moderate enantiomeric ratios (E), ranging up to E = 11.6, were obtained. In the resolution, some of the lipases selectively acylated the (+)-enant

Generation of γ-oxy-substituted benzylithium derivatives by reductive lithiation of 4-phenyl-1,3-dioxanes

Azzena, Ugo,Pilo, Luciano

, p. 664 - 668 (2007/10/03)

Reductive cleavage of 1,3-dioxanes 1a-c with Li metal in the presence of a catalytic amount of naphthalene in THF, followed by reaction with different electrophiles, allowed the synthesis of 3-substituted- and 3,3-disubstituted- 3-phenylpropan-1-ols 4 in good yields.
