Check Digit Verification of cas no

The CAS Registry Mumber 152770-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,7,7 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 152770-72:
(8*1)+(7*5)+(6*2)+(5*7)+(4*7)+(3*0)+(2*7)+(1*2)=134
134 % 10 = 4
So 152770-72-4 is a valid CAS Registry Number.

Synthesis of 1,2,4-Triazolines and triazoles utilizing oxazolones

Saleem, Rahman Shah Zaib,Tepe, Jetze J.

, p. 4330 - 4332 (2010)

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.
