General Description
"(R)-2,2',3,3'-Tetrahydro-6,6'-bis(triphenylsilyl)-1,1'-spirobi[1H-indene]-7,7'-diol, 99% e.e." is a chemical compound with high enantiomeric excess (e.e.) purity. It is a spirobiindane derivative that contains two triphenylsilyl groups. (R)-2,2',3,3'-Tetrahydro-6,6'-bis(triphenylsilyl)-1,1'-spirobi[1H-indene]-7,7'-diol,99%e.e. is a chiral molecule, meaning it has a non-superimposable mirror image, and the (R)-enantiomer is the predominant form in this sample. It is commonly used as a chiral ligand in asymmetric synthesis and catalysis, particularly in organic chemistry and pharmaceutical research. The high purity of the (R)-enantiomer makes it a valuable tool for enantioselective transformations and the production of optically pure compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 1372719-97-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,2,7,1 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1372719-97:
(9*1)+(8*3)+(7*7)+(6*2)+(5*7)+(4*1)+(3*9)+(2*9)+(1*7)=185
185 % 10 = 5
So 1372719-97-5 is a valid CAS Registry Number.
