Check Digit Verification of cas no
The CAS Registry Mumber 1256805-99-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,8,0 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1256805-99:
(9*1)+(8*2)+(7*5)+(6*6)+(5*8)+(4*0)+(3*5)+(2*9)+(1*9)=178
178 % 10 = 8
So 1256805-99-8 is a valid CAS Registry Number.

Photochemical synthesis and properties of axially chiral naphthylpyridines
Wessig, Pablo,Pick, Charlotte
experimental part, 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.
