Check Digit Verification of cas no

The CAS Registry Mumber 1338920-68-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,9,2 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1338920-68:
(9*1)+(8*3)+(7*3)+(6*8)+(5*9)+(4*2)+(3*0)+(2*6)+(1*8)=175
175 % 10 = 5
So 1338920-68-5 is a valid CAS Registry Number.

Photochemical synthesis and properties of axially chiral naphthylpyridines

Wessig, Pablo,Pick, Charlotte

scheme or table, p. 263 - 265 (2012/07/13)

Five alkynyl pyridines were prepared and cyclized to naphthylpyridines as the main products in the course of a Photo-Dehydro-Diels-Alder reaction. Four of the final products are axially chiral and the determination of the rotational barrier by DFT calculations, dynamic NMR and HPLC experiments is demonstrated.
