Check Digit Verification of cas no

The CAS Registry Mumber 79314-43-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,3,1 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 79314-43:
(7*7)+(6*9)+(5*3)+(4*1)+(3*4)+(2*4)+(1*3)=145
145 % 10 = 5
So 79314-43-5 is a valid CAS Registry Number.

Direct Amidation of Carboxylic Acids through an Active α-Acyl Enol Ester Intermediate

Xu, Xianjun,Feng, Huangdi,Huang, Liliang,Liu, Xiaohui

, p. 7962 - 7969 (2018/06/18)

The development of a highly efficient and simple protocol for the direct amidation of carboxylic acids is described employing ynoates as novel coupling reagents. The transformation proceeds in good to excellent yields via in situ α-acyl enol ester intermediates formation under mild reaction conditions. This useful method has been demonstrated for a range of substrates to provide a succinct access to structurally diverse amides, including key intermediates of glibenclamide, tiapride hydrochloride, and nateglinide, and can be conducted on a mole scale.
