1228801-85-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1228801-85-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,8,0 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1228801-85:
(9*1)+(8*2)+(7*2)+(6*8)+(5*8)+(4*0)+(3*1)+(2*8)+(1*5)=151
151 % 10 = 1
So 1228801-85-1 is a valid CAS Registry Number.

Synthesis of 1,2,4-Triazolines and triazoles utilizing oxazolones
Saleem, Rahman Shah Zaib,Tepe, Jetze J.
experimental part, p. 4330 - 4332 (2010/09/03)
We describe herein a convenient method for the synthesis of 1,2,4-triazolines using oxazolones and azodicarboxylates. Subsequent treatment of these 1,2,4-triazolines with NaOH provides efficient access to the corresponding triazoles.
