Check Digit Verification of cas no

The CAS Registry Mumber 155639-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,6,3 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 155639-31:
(8*1)+(7*5)+(6*5)+(5*6)+(4*3)+(3*9)+(2*3)+(1*1)=149
149 % 10 = 9
So 155639-31-9 is a valid CAS Registry Number.

Influence of amine substituents on 5-HT2A versus 5-HT2C binding of phenylalkyl- and indolylalkylamines

Glennon,Dukat,El-Bermawy,Law,De los Angeles,Teitler,King,Herrick-Davis

, p. 1929 - 1935 (1994)

The effect of 15 different amine substituents on 5-HT2A and 5-HT2C serotonin receptor binding was investigated for two series of compounds (i.e., phenylalkylamine and indolylalkylamine derivatives). In general, amine substitution decreases receptor affinity; however, N-(4-bromobenzyl) substitution results in compounds that bind at 5-HT2A receptors with high affinity (K(i) 100-fold selectivity. Although parallel structural modifications in the two series result in parallel shifts in 5- HT2C binding, these same modifications alter 5-HT2A binding in a less consistent manner.
