Check Digit Verification of cas no
The CAS Registry Mumber 452972-09-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,2,9,7 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 452972-09:
(8*4)+(7*5)+(6*2)+(5*9)+(4*7)+(3*2)+(2*0)+(1*9)=167
167 % 10 = 7
So 452972-09-7 is a valid CAS Registry Number.

New shelf-stable halo- and alkoxy-substituted pyridylboronic acids and their suzuki cross-coupling reactions to yield heteroarylpyridines
Parry, Paul R.,Bryce, Martin R.,Tarbit, Brian
, p. 1035 - 1038 (2007/10/03)
New shelf-stable pyridylboronic acids have been synthesized: bromine-lithium exchange followed by reaction with triisopropylborate (TIPB) yielded 2-fluoro-5-pyridylboronic acid (4), 3-bromo-5-pyridylboronic acid (5) and 2-ethoxy-5-pyridylboronic acid (6);
