Check Digit Verification of cas no
The CAS Registry Mumber 132548-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,5,4 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 132548-91:
(8*1)+(7*3)+(6*2)+(5*5)+(4*4)+(3*8)+(2*9)+(1*1)=125
125 % 10 = 5
So 132548-91-5 is a valid CAS Registry Number.

Axially Chiral Biaryl Monophosphine Oxides Enabled by Palladium/WJ-Phos-Catalyzed Asymmetric Suzuki-Miyaura Cross-coupling

, p. 1548 - 1554 (2020/02/04)
A highly enantioselective palladium/WJ-Phos-catalyzed Suzuki-Miyaura coupling reaction for efficient construction of axially chiral biaryl monophosphine oxides was developed. A series of axially chiral biaryl monophosphine oxides were obtained in good yields and with high enantioselectivities. The practicability of this reaction was validated in the straightforward synthesis of axially chiral biaryl monophosphine ligand and demonstrated by a 100-g-scale synthesis. Moreover, various functionalizations of the product make it as a platform molecule for synthesis of other chiral biaryl phosphines.
