129227-20-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129227-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,2,2 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 129227-20:
(8*1)+(7*2)+(6*9)+(5*2)+(4*2)+(3*7)+(2*2)+(1*0)=119
119 % 10 = 9
So 129227-20-9 is a valid CAS Registry Number.

Synthesis of 2-Aryltriazolobenzoxazoles by Oxidative Cyclization of N-(Benzoxazol-2-yl)benzamidines
Sambaiah, T.,Reddy, K. Kondal
, p. 422 - 424 (2007/10/02)
The reaction of 2-aminobenzoxazoles with benzonitriles in the presence of anhydrous tin(IV) chloride gives N-(benzoxazol-2-yl)benzamidines in high yields.Cyclodehydrogenation of these compounds with lead(IV) acetate affords 2-aryltriazoloben
