19141-19-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19141-19-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,1,4 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 19141-19:
(7*1)+(6*9)+(5*1)+(4*4)+(3*1)+(2*1)+(1*9)=96
96 % 10 = 6
So 19141-19-6 is a valid CAS Registry Number.

Six-membered bis(azaphosphorinane), readily available ligand for highly enantioselective asymmetric hydrogenations

Yan, Yongjun,Zhang, Xumu

, p. 1567 - 1569 (2006)

A new six-membered bis(azaphosphorinane) ligand has been readily prepared starting from an inexpensive chiral epoxide; excellent enantioselectivities (up to over 99% ee) have been achieved in the Rh-catalyzed asymmetric hydrogenations of β-dehydroamino ac

A chiral 1,2-bisphospholane ligand with a novel structural motif: Applications in highly enantioselective Rh-catalyzed hydrogenations

Tang, Wenjun,Zhang, Xumu

, p. 1612 - 1614 (2007/10/03)

TangPhos (1) is a highly efficient and practical ligand for asymmetric hydrogenations. High enantioselectivities and turnover numbers were observed in the Rh-catalyzed hydrogenation of α-(acylamino) acrylic acids and α-arylenamides.

Synthesis of 3, 4-O-Isopropylidene-(3S,4S)-dihydroxy-(2A,5R)-bis(diphenylphosphino)hexane and Its Application in Rh-Catalyzed Highly Enantioselective Hydrogenation of Enamides
