72197-20-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72197-20-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,1,9 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 72197-20:
(7*7)+(6*2)+(5*1)+(4*9)+(3*7)+(2*2)+(1*0)=127
127 % 10 = 7

, p. 8149 - 8151 (2007/10/03)
Alkyl-, alkenyl-, and arylboronic acids undergo Ag2O/CrCl2 mediated homocoupling in moderate to good yields under mild conditions. The general utility of this methodology is illustrated by an intramolecular annulation between sp and
