Check Digit Verification of cas no
The CAS Registry Mumber 2070902-77-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 2,0,7,0,9,0 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2070902-77:
(9*2)+(8*0)+(7*7)+(6*0)+(5*9)+(4*0)+(3*2)+(2*7)+(1*7)=139
139 % 10 = 9
So 2070902-77-9 is a valid CAS Registry Number.

Silver-Mediated Trifluoromethoxylation of (Hetero)aryldiazonium Tetrafluoroborates

Here we report a silver-mediated trifluoromethoxylation of (hetero)aryldiazonium tetrafluoroborates by converting an aromatic amino group into an OCF3 group. This method, which can be considered to be a trifluoromethoxylation variation of the classic Sandmeyer-type reaction, uses readily available aryl and heteroaromatic amines as starting materials and AgOCF3 as trifluoromethoxylating reagents. The broad substrate scope and simple, mild reaction condition made this transformation a valuable method in constructing aryl-OCF3 bonds.
