Check Digit Verification of cas no

The CAS Registry Mumber 56829-61-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,8,2 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 56829-61:
(7*5)+(6*6)+(5*8)+(4*2)+(3*9)+(2*6)+(1*1)=159
159 % 10 = 9
So 56829-61-9 is a valid CAS Registry Number.

, p. 1055 - 1069 (2007/10/03)

We previously described a series of N-(3-acyloxy-2-benzylpropyl) homovanillate and N′-(4-hydroxy-3-methoxybenzyl) thiourea derivatives that were potent VR1 agonists with high-affinities and excellent analgesic profiles. The design of these simplified RTX analogues was based on our RTX-derived pharmacophore model which incorporates the 4-hydroxy-3- methoxyphenyl (A-region), C20-ester (B-region), orthophenyl (C1-region) and C3-keto (C2-region) groups of RTX. For the purpose of optimizing the spatial arrangement of the four principal pharmacophores on the lead agonists (1-4), we have modified the distances in the parent C-region, 3-acyloxy-2-benzylpropyl groups, by lengthening or shortening one carbon to vary the distances between the pharmacophores. We find that two of the amides, 4 and 19, possess EC50 values i) and calcium influx (EC50) values. The binding affinities of the agonists correlated best with the RMS values derived from RTX conformation E (r2=0.92), predicting a model of the active conformation of RTX and related vanilloids for binding to VR1. Poorer correlation was obtained between any of the conformations and the EC 50 values for calcium influx.
