Check Digit Verification of cas no

The CAS Registry Mumber 190125-74-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,1,2 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 190125-74:
(8*1)+(7*9)+(6*0)+(5*1)+(4*2)+(3*5)+(2*7)+(1*4)=117
117 % 10 = 7
So 190125-74-7 is a valid CAS Registry Number.

CAL-B-mediated efficient synthesis of a set of valuable amides by direct amidation of phenoxy- and aryl-propionic acids

Benamara, Nourelhouda,Merabet-Khelassi, Mounia,Aribi-Zouioueche, Louisa,Riant, Olivier

, p. 4045 - 4053 (2021/04/21)

An efficient, easy and sustainable amidation of a set of non-activated carboxylic acids with anilines, assisted by CAL-B, as biodegradable catalyst, is reported. The enzymatic amidation reactions are performed on set of nonsteroidal anti-inflammatory drugs (NSAIDs), phenoxypropionic acid and protected-prolines by direct condensation of one equivalent of carboxylic acids and two equivalents of anilines derivatives in heptane after 72?h of reaction at 80?°C. The obtained carboxylic amides are recovered with isolated chemical yields varied between moderate and excellent. Fourteen from them are reported for the first time, and an X-ray crystal is obtained for: N-(4-iodophenyl)-2-(4-isobutylphenyl)propanamide 1d.
