General Description
"(4R)-2-Methyl-4,5,5-triphenyl-1,3,2-oxazaborolidine" is a chemical compound that contains the elements boron, oxygen, carbon, and hydrogen. It is a chiral oxazaborolidine, meaning it has a specific three-dimensional arrangement of atoms that gives it a unique chemical and biological activity. (4R)-2-Methyl-4,5,5-triphenyl-1,3,2-oxazaborolidine is often used as a catalyst in organic synthesis, particularly in asymmetric transformations, meaning it can facilitate chemical reactions in a way that produces only one of two possible mirror-image molecules. Its structure and properties make it useful in the production of pharmaceuticals, agrochemicals, and other fine chemicals. The "4R" designation indicates the stereochemistry at the fourth carbon atom, further specifying its three-dimensional arrangement.
Check Digit Verification of cas no
The CAS Registry Mumber 155268-88-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,2,6 and 8 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 155268-88:
(8*1)+(7*5)+(6*5)+(5*2)+(4*6)+(3*8)+(2*8)+(1*8)=155
155 % 10 = 5
So 155268-88-5 is a valid CAS Registry Number.
