265986-50-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 265986-50-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,5,9,8 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 265986-50:
(8*2)+(7*6)+(6*5)+(5*9)+(4*8)+(3*6)+(2*5)+(1*0)=193
193 % 10 = 3
So 265986-50-3 is a valid CAS Registry Number.

Fluorine-sacrificial cyclizations as an access to 5-fluoropyrazoles
Volle, Jean-Noel,Schlosser, Manfred
, p. 823 - 828 (2007/10/03)
Methyl 3-methoxy-2-trifluoromethylacrylate 1, readily prepared by Wittig reaction from methyl 3,3,3-trifluoropyruvate, has been treated with a number of aryl- (or hetaryl-) hydrazines. Under mild base-catalysis, the resulting 3-hydrazinoacrylates 6 underg
