Check Digit Verification of cas no

The CAS Registry Mumber 1258238-85-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,2,3 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1258238-85:
(9*1)+(8*2)+(7*5)+(6*8)+(5*2)+(4*3)+(3*8)+(2*8)+(1*5)=175
175 % 10 = 5
So 1258238-85-5 is a valid CAS Registry Number.

Preparation of Building Blocks for Iterative Suzuki-Miyaura Reactions via Direct Bromination of Aryl Boronic Acids: One-Pot Total Syntheses of Dictyoterphenyls A and B

Lee, Chun-Young,Cheon, Cheol-Hong

, p. 3831 - 3836 (2017)

A highly efficient method for the preparation of 4-alkoxy-3-bromophenyl boronic acid N-methyliminodiacetic acid (MIDA) esters as building blocks in iterative Suzuki-Miyaura reactions from the 4-alkoxyphenylboronic acids is described using a boronic acid m

Radical C?N Borylation of Aromatic Amines Enabled by a Pyrylium Reagent

Chabbra, Sonia,Cornella, Josep,Leutzsch, Markus,Ma, Yuanhong,Niski, Jan,Pang, Yue,Reijerse, Edward J.,Schnegg, Alexander

supporting information, (2020/03/23)

Herein, we report a radical borylation of aromatic amines through a homolytic C(sp2)?N bond cleavage. This method capitalizes on a simple and mild activation via a pyrylium reagent (ScPyry-OTf) thus priming the amino group for reacti
