121902-86-1 Usage
General Description
(S)-1,2-bis(diphenylphosphino)cyclohexylethane, also known as (S)-DPCHE, is a chiral diphosphine ligand commonly used in organic and inorganic chemistry. It consists of a cyclohexane ring with two diphenylphosphine groups attached in a trans configuration, resulting in a chiral structure. (S)-1,2-BIS(DIPHENYLPHOSPHINO)CYCLOHEXYLETHANE is widely used as a ligand in asymmetric synthesis, catalysis, and transition metal coordination chemistry. It has been shown to be effective in promoting various catalytic reactions, including hydrogenation, cross-coupling, and hydrosilylation. Its chiral nature allows for the production of enantiomerically pure compounds, making it a valuable tool in the synthesis of pharmaceuticals, agrochemicals, and fine chemicals.
Check Digit Verification of cas no
The CAS Registry Mumber 121902-86-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,9,0 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 121902-86:
(8*1)+(7*2)+(6*1)+(5*9)+(4*0)+(3*2)+(2*8)+(1*6)=101
101 % 10 = 1
So 121902-86-1 is a valid CAS Registry Number.
