57044-60-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57044-60-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,0,4 and 4 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 57044-60:
(7*5)+(6*7)+(5*0)+(4*4)+(3*4)+(2*6)+(1*0)=117
117 % 10 = 7
So 57044-60-7 is a valid CAS Registry Number.

Chakrabarty,Batabyal
, p. 1 - 10 (2007/10/02)
A convenient procedure for the mononitration of carbazole and 9-alkylcarbazoles using CAN in CH3CN in presence of SiO2 is reported. The results with 9-acetyl, 9-benzoyl and 9- benzenesulphonylcarbazoles are also discussed.
