It is a chiral compound, meaning it exists in two enantiomeric forms, with the (R)-enantiomer being the one that is specified in the compound's name. (R)-2,3-Dimethyl-4-(triphenylphosphoranylidene)-2-butanol is a phosphorane, which is a type of organophosphorus compound. It is commonly used as a reagent in organic synthesis, specifically in the formation of carbon-carbon and carbon-heteroatom bonds. Its structure consists of a central phosphorus atom bonded to three phenyl groups and a hydroxyl functional group, along with two methyl groups attached to the carbon atom adjacent to the hydroxyl group. (R)-2,3-Dimethyl-4-(triphenylphosphoranylidene)-2-butanol has applications in asymmetric synthesis and as a ligand in catalytic reactions.
Check Digit Verification of cas no
The CAS Registry Mumber 138079-58-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,0,7 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138079-58:
(8*1)+(7*3)+(6*8)+(5*0)+(4*7)+(3*9)+(2*5)+(1*8)=150
150 % 10 = 0
So 138079-58-0 is a valid CAS Registry Number.
