217099-16-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 217099-16-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,7,0,9 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 217099-16:
(8*2)+(7*1)+(6*7)+(5*0)+(4*9)+(3*9)+(2*1)+(1*6)=136
136 % 10 = 6
So 217099-16-6 is a valid CAS Registry Number.

Extremely fast gas/liquid reactions in flow microreactors: Carboxylation of short-lived organolithiums

Nagaki, Aiichiro,Takahashi, Yusuke,Yoshida, Jun-Ichi

, p. 7931 - 7934 (2014)

Carboxylation of short-lived organolithiums bearing electrophilic functional groups such as nitro, cyano, and alkoxycarbonyl groups with CO 2 to give carboxylic acids and active esters was accomplished in a flow microreactor system. The successful reactions indicate that gas/liquid mass transfer and the subsequent chemical reaction with CO2 are extremely fast. Carboxylation of short-lived organolithiums bearing electrophilic functional groups such as nitro, cyano, and alkoxycarbonyl groups with CO 2 to give carboxylic acids and active esters was accomplished in a flow microreactor system. The successful reactions indicate that gas/liquid mass transfer and the subsequent chemical reaction with CO2 are extremely fast (see scheme).
