Bis(diethylarsanyl)sulfide, also known as diethylarsine sulfide or (C2H5)2As-S-As(C2H5)2, is an organoarsenic compound characterized by the presence of two diethylarsanyl groups (As(C2H5)2) connected through a sulfur atom. This colorless, oily liquid is a derivative of diethylarsine, with the addition of a sulfur atom bridging the two arsenic centers. It is primarily used as a precursor in the synthesis of various organoarsenic compounds and has potential applications in the fields of pharmaceuticals, agrochemicals, and materials science. Due to its toxic nature and potential environmental impact, handling and disposal of bis(diethylarsanyl)sulfide must be done with caution and in accordance with proper safety protocols.
The CAS Registry Mumber 3136-28-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,3 and 6 respectively; the second part has 2 digits, 2 and 8 respectively. Calculate Digit Verification of CAS Registry Number 3136-28: (6*3)+(5*1)+(4*3)+(3*6)+(2*2)+(1*8)=65 65 % 10 = 5 So 3136-28-5 is a valid CAS Registry Number.
