Check Digit Verification of cas no
The CAS Registry Mumber 157021-61-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,0,2 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 157021-61:
(8*1)+(7*5)+(6*7)+(5*0)+(4*2)+(3*1)+(2*6)+(1*1)=109
109 % 10 = 9
So 157021-61-9 is a valid CAS Registry Number.

Direct trifluoromethylation of arenes using TFA as the trifluoromethylating reagent was achieved with Ag as the catalyst. This reaction not only provides a new protocol for aryl C-H trifluoromethylation, but the generation of CF3· from TFA may prove useful in other contexts and could potentially be extended to other trifluoromethylation reactions. (Chemical Equation Presented).
