948904-57-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 948904-57-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,8,9,0 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 948904-57:
(8*9)+(7*4)+(6*8)+(5*9)+(4*0)+(3*4)+(2*5)+(1*7)=222
222 % 10 = 2
So 948904-57-2 is a valid CAS Registry Number.

The syntheses of various 2-(4-aryl-2,4-dihydro-3-phenyl-1,2,4-triazol-3- ylidene)indan-1,3-diones are reported. The key to their successful synthesis depends on the reaction of amidrazones 1a-f with 2-(1,3-dioxoindan-2-ylidene) malononitrile (2).
