S-benzyl-isothiourea, with the chemical formula C8H10N2S, is an organic compound that features a benzyl group attached to an isothiourea moiety. It is often used in the synthesis of various pharmaceuticals and agrochemicals due to its reactivity and ability to form stable intermediates. On the other hand, heptadecafluoro-octane-1-sulfonate, with the chemical formula C8F17SO3-, is a perfluorinated compound characterized by a fully fluorinated octane chain and a sulfonate group. S-benzyl-isothiourea; heptadecafluoro-octane-1-sulfonate is known for its surfactant properties and is utilized in various industrial applications, including as a component in fire-fighting foams and as a surfactant in certain cleaning agents. Both chemicals, while different in structure and use, play significant roles in their respective fields.
The CAS Registry Mumber 423-57-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 3 respectively; the second part has 2 digits, 5 and 7 respectively. Calculate Digit Verification of CAS Registry Number 423-57: (5*4)+(4*2)+(3*3)+(2*5)+(1*7)=54 54 % 10 = 4 So 423-57-4 is a valid CAS Registry Number.
