216863-12-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 216863-12-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,8,6 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 216863-12:
(8*2)+(7*1)+(6*6)+(5*8)+(4*6)+(3*3)+(2*1)+(1*2)=136
136 % 10 = 6
So 216863-12-6 is a valid CAS Registry Number.

Palladium-catalyzed 1,4-addition of diarylphosphines to α,β-unsaturated N-acylpyrroles

Du, Dan,Duan, Wei-Liang

, p. 11101 - 11103 (2011/11/05)

Highly stereoselective asymmetric 1,4-addition of diarylphosphines to α,β-unsaturated N-acylpyrroles catalyzed by a PCP pincer-Pd complex has been developed for the synthesis of chiral phosphines with excellent stereoselectivity (91-99% ee) under mild con

A modular approach to ligands for asymmetric π-allyl palladium catalysed additions

Gilbertson, Scott R.,Chang, Cheng-Wei T.

, p. 975 - 976 (2007/10/03)

A route to phosphinodihydrooxazoles is reported, which is used to synthesize ten new ligands whose ability to asymmetrically catalyse the addition of dimethyl malonate to 1,3-diphenylprop-2-enyl acetate is investigated; the best gave a palladium complex w
