Check Digit Verification of cas no

The CAS Registry Mumber 218911-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,9,1 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 218911-25:
(8*2)+(7*1)+(6*8)+(5*9)+(4*1)+(3*1)+(2*2)+(1*5)=132
132 % 10 = 2
So 218911-25-2 is a valid CAS Registry Number.

Substituted pyrazoles as novel selective ligands for the human dopamine D4 receptor

Bourrain, Sylvie,Collins, Ian,Neduvelil, Joseph G.,Rowley, Michael,Leeson, Paul D.,Patel, Smita,Patel, Shil,Emms, Frances,Marwood, Rosemarie,Chapman, Kerry L.,Fletcher, Alan E.,Showell, Graham A.

Two novel series of 3-(heterocyclylmethyl)pyrazoles have been synthesised and evaluated as ligands for the human dopamine D4 receptor. Compounds in series I (exemplified by 8k) have a phenyl ring joined to the 4-position of the pyrazole while those in series II (exemplified by 15j) have a 5-phenyl ring linked by a saturated chain to the 4-position of the pyrazole. Both series supplied compounds with excellent affinity for the human D4 and good selectivity over other dopamine receptors. Excellent selectivity over calcium, sodium, and potassium ion channels was also achieved. Copyright (C) 1997 Elsevier Science Ltd.
