Check Digit Verification of cas no

The CAS Registry Mumber 70153-09-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,1,5 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 70153-09:
(7*7)+(6*0)+(5*1)+(4*5)+(3*3)+(2*0)+(1*9)=92
92 % 10 = 2
So 70153-09-2 is a valid CAS Registry Number.

A microwave-assisted highly practical chemoselective esterification and amidation of carboxylic acids

Pathak, Gunindra,Das, Diparjun,Rokhum, Lalthazuala

, p. 93729 - 93740 (2016)

The ubiquitousness of esters and amide functionalities makes their coupling reaction one of the most sought-after organic transformations. Herein, we have described an efficient microwave-assisted synthesis of esters and amides. Soluble triphenylphosphine, in conjugation with molecular iodine, gave the desired products without the requirement for a base/catalyst. In addition, a solid-phase synthetic route is incorporated for the said conversion, which has added advantages over solution-phase pathways, such as low moisture sensitivity, easy handling, isolation of the product by simple filtration, and reusability. In short, our method is simple, mild, green, and highly chemoselective in nature.
