92057-09-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92057-09-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,0,5 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 92057-09:
(7*9)+(6*2)+(5*0)+(4*5)+(3*7)+(2*0)+(1*9)=125
125 % 10 = 5
So 92057-09-5 is a valid CAS Registry Number.

Reactions of organolithiums with dialkyl oxalates. A flow microreactor approach to synthesis of functionalized α-keto esters
Nagaki, Aiichiro,Ichinari, Daisuke,Yoshida, Jun-Ichi
, p. 3242 - 3244 (2013)
Reactions of functionalized aryllithiums with dialkyl oxalates were achieved using a flow microreactor to obtain α-keto esters with high selectivity by virtue of fast 1:1 micromixing.
