Naphth[1,2-d]oxazole-5-sulfonic acid, 1,2-dihydro-2-thioxo-, also known as 1,2-dihydro-2-thioxonaphth[1,2-d]oxazole-5-sulfonic acid, is a complex organic compound with the chemical formula C9H7NO3S2. This molecule features a naphthalene core with an oxazole ring fused to it, a sulfur atom in the 5-position, and a sulfonic acid group attached to the same carbon. The 1,2-dihydro-2-thioxo part of the name indicates the presence of a saturated (dihydro) ring with a thioxo (sulfur-oxygen double bond) group. Naphth[1,2-d]oxazole-5-sulfonic acid, 1,2-dihydro-2-thioxo- is likely to be used in the synthesis of various organic compounds or as an intermediate in chemical reactions due to its unique structure and functional groups.

Check Digit Verification of cas no

The CAS Registry Mumber 7341-79-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,4 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7341-79:
(6*7)+(5*3)+(4*4)+(3*1)+(2*7)+(1*9)=99
99 % 10 = 9
So 7341-79-9 is a valid CAS Registry Number.
