Check Digit Verification of cas no

The CAS Registry Mumber 40950-04-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,5 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 40950-04:
(7*4)+(6*0)+(5*9)+(4*5)+(3*0)+(2*0)+(1*4)=97
97 % 10 = 7
So 40950-04-7 is a valid CAS Registry Number.

Paun, Anca,Zarafu, Irina,Caproiu, Miron T.,Draghici, Constantin,Maganu, Maria,Cotar, Ani I.,Chifiriuc, Mariana C.,Ionita, Petre

, p. 665 - 671 (2013/08/15)

Starting from benzocaine, a well-known anaesthetic, ten derivatives were synthesized and characterized by UV-vis, IR, NMR, and elemental analysis. Most of the compounds contain residues with recognized biological activity, like nicotinic acid (vitamin B3 or PP), biotin (vitamin B7 or H), lipoic acid (thioctic acid), adamantine, as well as other residues of crown-ether type, benzofurazane, naphtylurea, di- and tri-nitrobenzene, and a nitroxide radical. The biological evaluation of the obtained compounds included hydrophobicity (lipophobicity) assay, total antioxidant and microbiological activity tests.
