Check Digit Verification of cas no

The CAS Registry Mumber 1620330-18-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,3,3 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1620330-18:
(9*1)+(8*6)+(7*2)+(6*0)+(5*3)+(4*3)+(3*0)+(2*1)+(1*8)=108
108 % 10 = 8
So 1620330-18-8 is a valid CAS Registry Number.

Sustainable and recyclable magnetic nanocatalyst of 1,10-phenanthroline Pd(0) complex in green synthesis of biaryls and tetrazoles using arylboronic acids as versatile substrates

Bagherzadeh, Nastaran,Sardarian, Ali Reza,Eslahi, Hassan

, (2021)

A magnetic nanocatalyst was purveyed as a heterogeneous recoverable palladium-based catalyst anchored on green, sustainable and phosphine free support. Resulted Fe3O4@SiO2-Phen-Pd(0) nanocatalyst bearing powerful phenanthroline ligand was thoroughly characterized by physicochemical approaches like UV–vis, FT-IR, EDX, XRD, TGA, ICP, VSM, DLS, FESEM, and TEM analyses. After finding trustable data, the obtained magnetic catalyst was considered to be applied in the Suzuki-Miyaura type C-C couplings and getting corresponding tetrazoles using arylboronic acid derivatives as alternate precursors of aromatic halides and stupendous data were observed.

Atom-efficient synthesis of 2,4,6-trisubstituted 1,3,5-triazinesviaFe-catalyzed cyclization of aldehydes with NH4I as the sole nitrogen source

Liu, Qiang,Ren, Shuang,Xiao, Jiang

, p. 22230 - 22233 (2020/07/03)

An atom-efficient, straightforward method for the synthesis of 2,4,6-triaryl-1,3,5-triazinesviairon-catalyzed cyclization of aldehydes with NH4I as the sole nitrogen source is demonstrated. This strategy works smoothly under air atmosphere, and affords symmetrical 2,4,6-trisubstituted and unsymmetrical 1,3,5-triazines with yields from 18% to 72%. Compared to other methods, the present protocol provides a straightforward and atom-efficient approach to 2,4,6-trisubstituted 1,3,5-triazines using an inexpensive, easily available ammonium salt as the sole nitrogen source. Research into the preliminary mechanism indicates thatN-benzylidenebenzimidamides are involved in this cyclization reaction.
