1333164-48-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1333164-48-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,3,1,6 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1333164-48:
(9*1)+(8*3)+(7*3)+(6*3)+(5*1)+(4*6)+(3*4)+(2*4)+(1*8)=129
129 % 10 = 9
So 1333164-48-9 is a valid CAS Registry Number.

, p. 7081 - 7096 (2011/11/05)
5-Aryl-7-hydrazino-2-phenylpyrazolo[1,5-c]pyrimidines 1 were used as precursors for the preparation of a new series of 5-aryl-8-phenylpyrazolo[1,5-c] -1,2,4- triazolo[4,3-a]pyrimidines 2. The reactions of 2 with certain electrophilic reagents gave the res
