Check Digit Verification of cas no

The CAS Registry Mumber 499157-70-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,9,1,5 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 499157-70:
(8*4)+(7*9)+(6*9)+(5*1)+(4*5)+(3*7)+(2*7)+(1*0)=209
209 % 10 = 9
So 499157-70-9 is a valid CAS Registry Number.

experimental part, p. 1641 - 1658 (2010/04/29)

A series of 3-[2-{[(3-methyl-1-phenylbutyl)amino]carbonyl}-4-(phenoxymethyl)phenyl]propanoic acid analogs were synthesized and evaluated for their in vitro potency. In most cases, introduction of one or two substituents into the two phenyl moieties resulted in the tendency of an increase or retention of in vitro activities. Several compounds, which showed excellent subtype selectivity, were evaluated for their inhibitory effect against PGE2-induced uterine contraction in pregnant rats, which is thought to be mediated by the EP3 receptor subtype. The structure-activity relationships (SARs) are also discussed.
