1191241-58-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1191241-58-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,1,2,4 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1191241-58:
(9*1)+(8*1)+(7*9)+(6*1)+(5*2)+(4*4)+(3*1)+(2*5)+(1*8)=133
133 % 10 = 3
So 1191241-58-3 is a valid CAS Registry Number.

Synthesis and structure of 4-hydroxy-4-fluoroalkyl-1,4-dihydroimidazo[5,1- c][1,2,4]triazines
Shchegol'Kov,Sadchikova,Burgart,Saloutin
experimental part, p. 572 - 580 (2009/09/06)
Azo coupling of fluorinated 1,3-diketones with 4-ethoxycarbonyl-1H- imidazole-5-diazonium chloride led to the formation of 4-hydroxy-4- polyfluoroalkyl-1,4-dihydroimidazo[5,1-c][1,2,4]triazines. According to the 1H and 19F NMR data,
