2H-1-Benzopyran-2-carboxamide, 3,4-dihydro- is a chemical compound with the molecular formula C10H9NO2. It belongs to the class of benzopyran derivatives, which are heterocyclic compounds containing a benzene ring fused to a pyran ring. This specific compound features a carboxamide group (-CONH2) attached to the benzopyran structure, with the 3,4-dihydro prefix indicating that the molecule has two hydrogen atoms added to the 3 and 4 positions of the benzopyran ring, resulting in a saturated structure. It is an important intermediate in the synthesis of various pharmaceuticals and agrochemicals, particularly those containing the benzopyran scaffold.

Check Digit Verification of cas no

The CAS Registry Mumber 3990-58-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,9 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3990-58:
(6*3)+(5*9)+(4*9)+(3*0)+(2*5)+(1*8)=117
117 % 10 = 7
So 3990-58-7 is a valid CAS Registry Number.

Novel, broad-spectrum anticonvulsants containing a sulfamide group: Pharmacological properties of (S)- N -[(6-chloro-2,3-dihydrobenzo[1,4]dioxin-2- yl)methyl]sulfamide (JNJ-26489112)

Broad-spectrum anticonvulsants are of considerable interest as antiepileptic drugs, especially because of their potential for treating refractory patients. Such "neurostabilizers" have also been used to treat other neurological disorders, including migraine, bipolar disorder, and neuropathic pain. We synthesized a series of sulfamide derivatives (4-9, 10a-i, 11a, 11b, 12) and evaluated their anticonvulsant activity. Thus, we identified promising sulfamide 4 (JNJ-26489112) and explored its pharmacological properties. Compound 4 exhibited excellent anticonvulsant activity in rodents against audiogenic, electrically induced, and chemically induced seizures. Mechanistically, 4 inhibited voltage-gated Na+ channels and N-type Ca2+ channels and was effective as a K+ channel opener. The anticonvulsant profile of 4 suggests that it may be useful for treating multiple forms of epilepsy (generalized tonic-clonic, complex partial, absence seizures), including refractory (or pharmacoresistant) epilepsy, at dose levels that confer a good safety margin. On the basis of its pharmacology and other favorable characteristics, 4 was advanced into human clinical studies.
