216862-91-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 216862-91-8 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 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 216862-91:
(8*2)+(7*1)+(6*6)+(5*8)+(4*6)+(3*2)+(2*9)+(1*1)=148
148 % 10 = 8
So 216862-91-8 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
