690226-89-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 690226-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,0,2,2 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 690226-89:
(8*6)+(7*9)+(6*0)+(5*2)+(4*2)+(3*6)+(2*8)+(1*9)=172
172 % 10 = 2
So 690226-89-2 is a valid CAS Registry Number.

Chiral Silver Alkoxide Catalyzed Asymmetric Aldol Reaction of Alkenyl Esters with Isatins
Yanagisawa, Akira,Kawada, Aiko
, p. 1246 - 1252 (2021)
A catalytic enantioselective aldol reaction of alkenyl esters with isatins was achieved using a DM-BINAP·AgOTf complex as the chiral precatalyst and N, N -diisopropylethylamine as the base precatalyst in the presence of methanol or 2,2,2-trifluoroethanol.
