Check Digit Verification of cas no
The CAS Registry Mumber 847818-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,7,8,1 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 847818-68:
(8*8)+(7*4)+(6*7)+(5*8)+(4*1)+(3*8)+(2*6)+(1*8)=222
222 % 10 = 2
So 847818-68-2 is a valid CAS Registry Number.

Synthesis of pinacol esters of 1-alkyl-1H-pyrazol-5-yl- and 1-alkyl-1H-pyrazol-4-ylboronic acids

Starting from 1H-pyrazol, a wide number of 1-alkyl-1H-pyrazol-4-yl and 1-alkyl-1H-pyrazol-5-ylboronic acids and their pinacol esters were synthesized and characterized. The key step in the described methodology is the regioselective lithiation of the pyrazole ring. The synthesized pinacolates are stable under prolonged storage and can be used as convenient reagents in organic synthesis.
