256510-24-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 256510-24-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,5,1 and 0 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 256510-24:
(8*2)+(7*5)+(6*6)+(5*5)+(4*1)+(3*0)+(2*2)+(1*4)=124
124 % 10 = 4
So 256510-24-4 is a valid CAS Registry Number.

SYNTHESIS OF -TRIAZOLOBENZOXAZEPINES via INTRAMOLECULAR AZIDE CYCLOADDITION
Garanti, Luisa,Molteni, Giorgio,Zecchi, Gaetano
, p. 291 - 296 (2007/10/02)
Starting from isatoic anhydride and propargyl alcohols, we developed a synthetic approach to the title compounds, were the key step is an intramolecular cycloaddition of the azido group onto the acetylenic bond.
