Check Digit Verification of cas no

The CAS Registry Mumber 129177-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,7 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129177-99:
(8*1)+(7*2)+(6*9)+(5*1)+(4*7)+(3*7)+(2*9)+(1*9)=157
157 % 10 = 7
So 129177-99-7 is a valid CAS Registry Number.

STUDIES IN AZIDE CHEMISTRY. PART 14 . THERMOLYSIS OF PERFLUORO-4-AZIDOPYRIDINE AND PERFLUORO-4-AZIDOTOLUENE IN THE PRESENCE OF PENTA- AND HEXA-METHYLBENZENE

Banks, R. Eric,Madany, Ismail M.

, p. 527 - 532 (2007/10/02)

Thermolysis of perfluoro-4-azidopyridine and perfluoro-4-azidotoluene in the presence of a large excess (10 molar) of pentamethylbenzene gave mainly (>60percent) products expected from nitrene 'insertions' at the nuclear C-H bond, i.e.ArFNHC6Me5 (ArF = 4-C5F4N, 4-C6F4CF3).Similar decomposition of perfluoro-4-azidotoluene in hexamethylbenzene gave a complex mixture containing perfluoro-p-toluidine.
