260788-72-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 260788-72-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,0,7,8 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 260788-72:
(8*2)+(7*6)+(6*0)+(5*7)+(4*8)+(3*8)+(2*7)+(1*2)=165
165 % 10 = 5
So 260788-72-5 is a valid CAS Registry Number.

The application of stop-flow microwave technology to scaling-out S NAr reactions using a soluble organic base

Marafie, Jameel A.,Moseley, Jonathan D.

experimental part, p. 2219 - 2227 (2010/07/04)

A model SNAr reaction which gives a range of substituted diaryl ethers has been re-developed to function with the soluble organic base DBU in the place of insoluble potassium carbonate. Manufacture of these diaryl ethers has then been achieved by scaling-out in an automated stop-flow microwave reactor to give productivities of >0.5 kg per day. Analogous reaction partners have also been scaled up in this reactor to extend the scope of the study. Brief comparison in a scale-up batch microwave reactor is also made. Lastly, continuous 24 h processing is reported in this small microwave stop-flow reactor, which requires no manual intervention once started.
