70938-05-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 70938-05-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,9,3 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 70938-05:
(7*7)+(6*0)+(5*9)+(4*3)+(3*8)+(2*0)+(1*5)=135
135 % 10 = 5
So 70938-05-5 is a valid CAS Registry Number.

Synthesis of Fatty Acetoacetates Under Microwave Irradiation Catalysed by Sulfamic Acid in a Solvent-Free System

Weber, Andressa C. H.,Batista, Thaís C.,Gon?alves, Bruno,Hack, Carolina R. L.,Porciuncula, Larissa M.,Treptow, Tamara G. M.,D’Oca, Caroline Da R. Montes,Russowsky, Dennis,D’Oca, Marcelo G. Montes

The 1,3-dicarbonyl compounds are important building blocks to obtain products with various biological activities and technological applications. In this work, we used a simple transesterification method to develop fatty acetoacetates in a solvent-free medium using a green catalyst, sulfamic acid (NH2SO3H), under microwave irradiation. The experimental results demonstrate good yields in a short reaction time (13?min), which makes this method an efficient approach to synthesize fatty acetoacetates from a wide range of saturated, unsaturated, and polyunsaturated long chain fatty alcohols, and ricinoleic derivatives. Experiments of recycling of the catalyst were performed and no decrease in catalytic activity of sulfamic acid was observed.
