Check Digit Verification of cas no

The CAS Registry Mumber 240139-83-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,0,1,3 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 240139-83:
(8*2)+(7*4)+(6*0)+(5*1)+(4*3)+(3*9)+(2*8)+(1*3)=107
107 % 10 = 7
So 240139-83-7 is a valid CAS Registry Number.

Novel compounds and their use as positive AMPA receptor modulators

-

, (2008/06/13)

The invention provides novel compounds represented by the general formula 5 compound represented by the formula: wherein the bond represented by the broken line may be a single, a double bond or absent; and if the bond is absent, then the nitrogen is substituted with a hydrogen and R2; X represents SO2 or C═O or CH2; Y represents —CH(R4)—, —N(R4)— or —N(R4)—CH2—, O; and the meaning of R2, R3, R4, R5, R6, R7, and R8 are as defined in the application The compounds are useful as positive modulators of the AMPA-receptor.
