Check Digit Verification of cas no

The CAS Registry Mumber 261-05-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,6 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 261-05:
(5*2)+(4*6)+(3*1)+(2*0)+(1*5)=42
42 % 10 = 2
So 261-05-2 is a valid CAS Registry Number.

INTRAMOLECULAR NITRENE INSERTIONS INTO AROMATIC AND HETEROAROMATIC RINGS. PART 8. FLASH VACUUM PYROLYSIS OF 2-AZIDOBENZYLPYRIDINES

Hicks, Martin G.,Jones, Gurnos.,York, David C.

, p. 69 - 76 (2007/10/02)

Flash vacuum pyrolysis of 2-azidobenzylpyridines (9)-(11) at temperatures from 350 to 700 deg C gave mixtures of benzonaphthyridines and their dihydro derivatives as major products.The 3-pyridyl derivative (10) also gave 2-(3-cyanoprop-1-enyl)indole (19).Benzonaphthyridines were also obtained by pyrolysis of 2-aminophenyl(x-pyridyl)methanols (4), (5), and (6), .Treatment of the azides (9)-(11) with aluminium chloride gave the corresponding 2-amino-5-chlorobenzylpyridines (21)-(23).The mechanism of the reaction is discussed.
