81450-33-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81450-33-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,5 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81450-33:
(7*8)+(6*1)+(5*4)+(4*5)+(3*0)+(2*3)+(1*3)=111
111 % 10 = 1
So 81450-33-1 is a valid CAS Registry Number.

, p. 1523 - 1527 (2007/10/02)
The synthesis of 1,2,4-triazolopyridazines and the unknown ring system, pyrazino-1,2,4-triazolopyridazine, has been achieved.The preparation of the new tricyclic 1,2,4-triazole was accomplished first by ring closure of the triazole ri
