Check Digit Verification of cas no
The CAS Registry Mumber 81303-59-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,3,0 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81303-59:
(7*8)+(6*1)+(5*3)+(4*0)+(3*3)+(2*5)+(1*9)=105
105 % 10 = 5
So 81303-59-5 is a valid CAS Registry Number.

Herein, we present a facile approach to a diverse collection of 1,4-disubstituted 3-di- or mono-fluoromethylpyrazoles utilizing our previously developed cyanopyrazoles as key building blocks. This method features several merits, such as easily accessible starting materials, broad substrate scope, mild reaction conditions, and simple operation. This protocol further deserves to be highlighted by the successful translation into the synthesis of commercialized fungicide fluxapyroxad and its analogues.
