Check Digit Verification of cas no

The CAS Registry Mumber 288621-65-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,8,6,2 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 288621-65:
(8*2)+(7*8)+(6*8)+(5*6)+(4*2)+(3*1)+(2*6)+(1*5)=178
178 % 10 = 8
So 288621-65-8 is a valid CAS Registry Number.

The role of the side chain in determining relative δ- and κ-affinity in C5′-substituted analogues of naltrindole

Black, Shannon L.,Jales, Andrew R.,Brandt, Wolfgang,Lewis, John W.,Husbands, Stephen M.

, p. 314 - 317 (2007/10/03)

The role of the side chain in 5′-substituted analogues of naltrindole has been further explored with the synthesis of series of amides, amidines, and ureas. Amidines (8, 13) had greatest selectivity for the K receptor, as predicted from consideration of the message-address concept. It was also found that an appropriately located carbonyl group, in ureas (10) and amides (7), led to retention of affinity and antagonist potency at the δ receptor.
