Check Digit Verification of cas no

The CAS Registry Mumber 153034-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,0,3 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 153034-91:
(8*1)+(7*5)+(6*3)+(5*0)+(4*3)+(3*4)+(2*9)+(1*1)=104
104 % 10 = 4
So 153034-91-4 is a valid CAS Registry Number.

Iterative and regioselective cross-couplings of 2-chloro-3,4-diiodopyridine leading to 2,3,4-triheteroarylpyridines

Daykin, Laura M.,Siddle, Jamie S.,Ankers, Adrian L.,Batsanov, Andrei S.,Bryce, Martin R.

supporting information; experimental part, p. 668 - 675 (2010/09/05)

A one-pot synthesis of 2-chloro-3,4-diiodopyridine from 2-chloropyridine is described via a Directed ortho Metallation (DoM)/Halogen Dance (HD) mechanism in 26-28% yields. By performing sequential, iterative Suzuki-Miyaura cross-couplings using a variety of functionalised heteroaryl and arylboronic acids, a series of novel 2,3,4-triheteroarylpyridine scaffolds have been accessed in synthetically viable yields, including sterically hindered derivatives. 2-Chloro-4-heteroaryl-3-iodopyridines and 2-chloro-3,4-diheteroarylpyridines are also reported. The synthesis of 5-[3,4-bis(2-phenylethynyl)pyridin-2-yl]-2-fluoropyridine via a two-step Sonogashira/Suzuki-Miyaura reaction sequence from 2-chloro-3,4-diiodopyridine, phenylacetylene and 6-fluoropyridin-3-yl-3-boronic acid has been achieved in 48% overall yield.
