Check Digit Verification of cas no

The CAS Registry Mumber 132048-37-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,0,4 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 132048-37:
(8*1)+(7*3)+(6*2)+(5*0)+(4*4)+(3*8)+(2*3)+(1*7)=94
94 % 10 = 4
So 132048-37-4 is a valid CAS Registry Number.

Covalent organic framework supported Pd(II)-catalyzed conjugate additions of arylboronic acids to α,β-unsaturated carboxylic acids

, (2021/04/28)

A palladium(II)-coordinated covalent organic framework (Pd(II)@COF) was mechanochemically synthesized from [2,2′-bipyridine]-5,5′-diamine (Bpy) and 1,3,5-triformylphloroglucinol (Tp), which was demonstrated as a catalyst for conjugate addition of arylboronic acids to unreactive α,β-unsaturated carboxylic acids in aqueous media (water/acetone = 1:1). Modest to good yields were obtained for most substrates, and studies on the catalyst recyclability showed that the heterogeneous catalyst gave >80% yields in the first 4 cycles. This research broadens the application of COFs supported catalysis and gave a new option for Pd(II)-catalysis.
