15656-74-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 15656-74-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,6,5 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 15656-74:
(7*1)+(6*5)+(5*6)+(4*5)+(3*6)+(2*7)+(1*4)=123
123 % 10 = 3
So 15656-74-3 is a valid CAS Registry Number.

Novel method for preparing fluorination reagent and its application to synthesis of fluoropyridazinones
Pei, Wen,Yang, Wei
, p. 535 - 539 (2010)
4-Chloro-5-fluoro-2-aryl-3(2H)-pyridazinones were obtained by the fluorination of 4,5-dichloro-2-aryl-3(2H)-pyridazinones with ethylhexamethylenetetramine fluoride in excellent yields. The ethylhexamethylenetetramine fluoride was synthesized by the reacti
