Check Digit Verification of cas no

The CAS Registry Mumber 20734-66-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,3 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 20734-66:
(7*2)+(6*0)+(5*7)+(4*3)+(3*4)+(2*6)+(1*6)=91
91 % 10 = 1
So 20734-66-1 is a valid CAS Registry Number.

Identification of novel matrix metalloproteinase inhibitors by screening of phenol fragments library

Rubino, Maria Teresa,Maggi, Dariana,Laghezza, Antonio,Loiodice, Fulvio,Tortorella, Paolo

experimental part, p. 557 - 563 (2012/06/30)

In the last 20 years, a great variety of synthetic, low molecular weight MMP inhibitors (MMPIs) have been synthesized and tested, although none has reached clinical utility. Exploration of novel ZBGs and development of non-hydroxamate MMPI has become a focus in current research. It's well-known that polyphenols can produce beneficial effects on human health by their antioxidant properties as well as they have the ability to block gelatinase activity. In this work we tested a series of selected phenols as MMP inhibitors. The most interesting hit (B6) shows sub-micromolar activity against MMP-2 (IC50 0.59 ± 0.05 μM, LE = 1.07) and a fairly good selectivity spectrum. A screening of selected phenols against four matrix metalloproteinases is reported. Eight phenols showed a very interesting activity and selective profile. The most interesting hit (B6) presents a sub-micromolar activity against MMP-2 (IC50 0.59±0.05μM). Copyright
