Check Digit Verification of cas no

The CAS Registry Mumber 854373-97-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,4,3,7 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 854373-97:
(8*8)+(7*5)+(6*4)+(5*3)+(4*7)+(3*3)+(2*9)+(1*7)=200
200 % 10 = 0
So 854373-97-0 is a valid CAS Registry Number.

2-Ethoxy-3-pyridylboronic acid: A versatile reagent for the synthesis of highly-functionalised 3-aryl/heteroaryl-pyridines via Suzuki cross-coupling reactions

Thompson, Amy E.,Batsanov, Andrei S.,Bryce, Martin R.,Saygili, Nezire,Parry, Paul R.,Tarbit, Brian

, p. 5131 - 5135 (2005)

This paper describes the commercially-viable synthesis and isolation of 2-ethoxy-3-pyridylboronic acid on a ca. 70 g scale via a directed ortho-metalation reaction on readily-available 2-ethoxypyridine. A range of efficient cross-coupling reactions of 2-ethoxy-3-pyridylboronic acid with selected aryl/heteroaryl halides under palladium-catalysed Suzuki-Miyaura conditions yield novel 2-ethoxy-3-aryl/heteroaryl-pyridines in high yield (heteroaryl=pyridyl, pyrimidyl, pyrazyl). The X-ray crystal structure of 2-ethoxy-3-pyridylboronic acid reveals that the boronic acid group takes part in an intramolecular O-H?O bond with the adjacent ethoxy substituent, and an intermolecular O-H?N bond.
