Check Digit Verification of cas no

The CAS Registry Mumber 1428343-35-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,3,4 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1428343-35:
(9*1)+(8*4)+(7*2)+(6*8)+(5*3)+(4*4)+(3*3)+(2*3)+(1*5)=154
154 % 10 = 4
So 1428343-35-4 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

, p. 4634 - 4636 (2013)

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.
