1026635-58-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1026635-58-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,6,6,3 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1026635-58:
(9*1)+(8*0)+(7*2)+(6*6)+(5*6)+(4*3)+(3*5)+(2*5)+(1*8)=134
134 % 10 = 4
So 1026635-58-4 is a valid CAS Registry Number.

One pot synthesis of N-aryl-5-aryl-2-furoyl amides via reaction of 5-aryl-2-furoic acid with arylamines
Li, Zheng,Wang, Xicun
, p. 3357 - 3362 (2002)
The N-aryl-5-aryl-2-furoyl amides (3a-r) are synthesized by one pot method via reaction of 5-aryl-2-furoic acids (1) with arylamines, using phenylsulfonyl chloride as reagent, under solid-liquid phase transfer catalysis in excellent yield.
