1,3-bis(2,6-dithiacyclohexyl)propane, also known as 1,3-bis(2,6-dimercaptophenyl)propane or simply "Lawesson's reagent," is a chemical compound with the formula C15H20S4. It is a colorless to pale yellow crystalline solid that is widely used as a reagent in organic synthesis, particularly for the conversion of various functional groups, such as ketones, aldehydes, and esters, into their corresponding thio analogs. The reagent is named after Swedish chemist Stig I. Lundgren, who first synthesized it in 1968. Its structure consists of a propane chain with two 2,6-dithiacyclohexyl groups attached to the terminal carbon atoms, which provides its unique reactivity and versatility in various chemical transformations.

Check Digit Verification of cas no
The CAS Registry Mumber 4883-05-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,8 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.Calculate Digit Verification of CAS Registry Number 4883-05:
(6*4)+(5*8)+(4*8)+(3*3)+(2*0)+(1*5)=110
110 % 10 = 0
So 4883-05-0 is a valid CAS Registry Number.
