Check Digit Verification of cas no

The CAS Registry Mumber 1432998-28-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,2,9,9 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1432998-28:
(9*1)+(8*4)+(7*3)+(6*2)+(5*9)+(4*9)+(3*8)+(2*2)+(1*8)=191
191 % 10 = 1
So 1432998-28-1 is a valid CAS Registry Number.

Pd-catalyzed C3-selective arylation of pyridines with phenyl tosylates

Dai, Fenglin,Gui, Qingwen,Liu, Jidan,Yang, Zhiyong,Chen, Xiang,Guo, Ruqing,Tan, Ze

supporting information, p. 4634 - 4636 (2013/06/05)

We have discovered that phenyl tosylates can be used to arylate pyridines at the C3-position using a Pd(OAc)2-1,10-phenanthroline catalyst system. We also discovered that the reaction of 4-methylpyridine with naphthyl tosylates occurred on the methyl group instead of at the C3-position. The Royal Society of Chemistry 2013.
