Check Digit Verification of cas no

The CAS Registry Mumber 149117-40-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,1,1 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 149117-40:
(8*1)+(7*4)+(6*9)+(5*1)+(4*1)+(3*7)+(2*4)+(1*0)=128
128 % 10 = 8
So 149117-40-8 is a valid CAS Registry Number.

Synthesis and antifungal activity of d-glucopyranosyl ureas and d-glucofurano-imidazolidine-2-ones

Tang, Xuan,Xue, Feng,Ma, Hongju,Cao, Xiufang,Chen, Changshui,Li, Xuegang

, p. 805 - 820 (2013/06/05)

A series of N-β-d-glucopyranosyl-N'-substituted phenyl ureas were synthesized by reaction of glucosyl isocyanate with arylamines and glycosamine with aryl isocyanates, and a series of d-glucofurano-imidazolidine-2-ones were obtained via deacetylation of glycosylureas. Although some of the compounds have already been described, most were prepared for the first time in this work. The structures of all the compounds synthesized were confirmed by IR, 1H NMR, and, in part, by 13C NMR. Antifungal activity of the title compounds was determined against four kinds of plant pathogenic fungi, Sclerotinia sclerotiorum, Fusarium graminearum, Fusarium oxysporum, and Bipolaris maydis. Preliminary bioassay indicates that most of glycosylureas had some activity against S. sclerotiorum; for some, the antifungal activity was strong. However, most of the imidazolidine-2-ones had weak antifungal activity.
