Check Digit Verification of cas no

The CAS Registry Mumber 1243253-28-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,3,2,5 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1243253-28:
(9*1)+(8*2)+(7*4)+(6*3)+(5*2)+(4*5)+(3*3)+(2*2)+(1*8)=122
122 % 10 = 2
So 1243253-28-2 is a valid CAS Registry Number.

MCHR1 antagonists are provided having the following Formula (I): A 1 and A 2 are independently C or N, E is C or N, Q 1 , Q 2 , and Q 3 are independently C or N provided that at least one of Q 1 , Q 2 , and Q 3 is N but not more than one of Q 1 , Q 2 , and Q 3 is N, D 1 is a bond, -CR 8 R 9 X-, -XCR 8 R 9 -, -CHR 8 CHR 9 -, -CR 10 =CR 10' -, -C-C-, or 1,2-cyclopropyl; X is O, S or NR 11, R 1 , R 2 , and R 3 are ,independently selected from the group consisting of hydrogen, halogen, lower alkyl, lower cycloalkyl, -CF 3 , -OCF 3 , -OR 12 and -SR 12, G is O, S or -NR 15, D 2 is lower alkyl, lower cycloalkyl, lower alkylcycloalkyl, lower cycloalkylalkyl, lower cycloalkoxyalkyl or lower alkylcycloalkoxy or when G is NR 15 , G and D 2 together may optionally form an azetidine, pyrrolidine or piperidine ring; Z 1 and Z 2 are independently hydrogen, lower alkyl, lower cycloalkyl, lower alkoxy, lower cycloalkoxy, halo, -CF 3 , -OCONR 14 R 14' , -CN, -CONR 14 R 14' , -SOR 12 , -SO 2 R 12 , -NR 14 COR 14' , -NR 14 CO 2 R 14' , -CO 2 R 12 , NR 14 SO 2 R 12 or COR 12 ; R 5 , R 6 , and R 7 are independently selected from the group consisting of hydrogen lower alkyl, lower cycloalkyl, -CF 3 , -SR 12 , lower alkoxy, lower cycloalkoxy, -CN, -CONR 14 R 14' , SOR 12 , SO 2 R 12 , NR 14 COR 14' , NR 14 CO 2 R 12 , CO 2 R 12 , NR 14 SO 2 R 12 and -COR 12 ; R 8 , R 9 , R 10 , R 10' , R 11 are independently hydrogen or lower alkyl; R 12 is lower alkyl or lower cycloalkyl; R 14 and R 14' are independently H, lower alkyl, lower cycloalkyl or R 14 and R 14' together with the N to which they are attached form a ring having 4 to 7 atoms; and R 15 is independently selected from the group consisting of hydrogen and lower alkyl. Such compounds are useful for the treatment of MCHR1 mediated diseases, such as obesity, diabetes, IBD, depression, and anxiety
