1204330-99-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1204330-99-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,3,3 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1204330-99:
(9*1)+(8*2)+(7*0)+(6*4)+(5*3)+(4*3)+(3*0)+(2*9)+(1*9)=103
103 % 10 = 3
So 1204330-99-3 is a valid CAS Registry Number.

Synthesis of 4,5-disubstituted-3-trihalomethylisothiazoles
Zawistoski, Michael P.,Decker, Shannon M.,Griffith, David A.
, p. 7286 - 7287 (2009)
Herein, we describe the synthesis of 4,5-disubstituted-3-trihalomethylisothiazoles from trihaloacetonitriles and 2-cyanothioacetamides or 2-ethoxycarbonylthioacetamides. The reactivity of the necessary trihaloacetonitriles has a significant impact on the
