156684-91-2 Usage

General Description

2,3-Difluoro-4-pentyloxyphenylboronic acid is a type of boronic acid, a class of compounds containing a boron atom. The presence of the difluoro group indicates that the molecule has two fluorine atoms, and the term '4-pentyloxyphenyl' refers to a phenyl group (a ring-shaped formation of carbon atoms) possessing a pentyloxy group (five carbon atoms and an oxygen atom) attached to it. Boronic acids, including 2,3-Difluoro-4-pentyloxyphenylboronic acid, have applications in many areas of chemistry including materials science, medicine, and biology. They are widely used as catalysts, building blocks, and protective groups.

Check Digit Verification of cas no

The CAS Registry Mumber 156684-91-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,6,8 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 156684-91:
(8*1)+(7*5)+(6*6)+(5*6)+(4*8)+(3*4)+(2*9)+(1*1)=172
172 % 10 = 2
So 156684-91-2 is a valid CAS Registry Number.
