Check Digit Verification of cas no

The CAS Registry Mumber 77167-05-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,6 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77167-05:
(7*7)+(6*7)+(5*1)+(4*6)+(3*7)+(2*0)+(1*5)=146
146 % 10 = 6
So 77167-05-6 is a valid CAS Registry Number.

Intramolecular Aminoazidation of Unactivated Terminal Alkenes by Palladium-Catalyzed Reactions with Hydrogen Peroxide as the Oxidant

Beccalli, Egle M.,Broggini, Gianluigi,Foschi, Francesca,Lo Presti, Leonardo,Loro, Camilla,Oble, Julie,Poli, Giovanni,Sala, Roberto

supporting information, (2020/02/28)

The palladium-catalyzed aminoazidation of aminoalkenes yielding azidomethyl-substituted nitrogen-containing heterocycles was developed. The procedure requires oxidative conditions and occurs at room temperature in the presence of hydrogen peroxide and NaN3 as the azide source. These conditions provide selective exo-cyclization/azidation of the carbon-carbon double bond, furnishing a versatile approach toward five-, six-, and seven-membered heterocyclic rings.
