476620-20-9 Usage

Uses

4-Methylthiophene-3-boronic acid pinacol ester is a useful reactant for the synthesis of aryl/heteroaryl/alkenyl borates.

Check Digit Verification of cas no

The CAS Registry Mumber 476620-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,6,6,2 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 476620-20:
(8*4)+(7*7)+(6*6)+(5*6)+(4*2)+(3*0)+(2*2)+(1*0)=159
159 % 10 = 9
So 476620-20-9 is a valid CAS Registry Number.
