Check Digit Verification of cas no

The CAS Registry Mumber 509142-47-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,9,1,4 and 2 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 509142-47:
(8*5)+(7*0)+(6*9)+(5*1)+(4*4)+(3*2)+(2*4)+(1*7)=136
136 % 10 = 6
So 509142-47-6 is a valid CAS Registry Number.

, p. 3307 - 3319 (2007/10/03)

The optimization of the distance between two key pharmacophore features within our first hit compounds 1a and 2a led to the identification of a new class of potent non-peptidic antagonists for the MCH-R1, based around 4-amino-2-cyclohexylaminoquinazolines. In particular, ATC0065 (2c), N2-[cis-4-({2-[4-Bromo-2-(trifluoromethoxy)phenyl]ethyl}amino)cyclohexyl]-N4,N4-dimethylquinazoline-2,4-diamine dihydrochloride, bound with high affinity to the MCH-R1 (IC50 value of 16 nM) and showed good metabolic stability in liver microsomes from human and rat.
