102697-43-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 102697-43-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,6,9 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 102697-43:
(8*1)+(7*0)+(6*2)+(5*6)+(4*9)+(3*7)+(2*4)+(1*3)=118
118 % 10 = 8
So 102697-43-8 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
supporting information, p. 3242 - 3244 (2013/05/08)
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.
