1,4-Bis-(4-acetoxy-butyloxy)-butan, also known as 1,4-bis(4-acetoxybutoxy)butane, is a chemical compound with the molecular formula C16H28O6. It is a colorless liquid at room temperature and is soluble in most organic solvents. 1,4-Bis-(4-acetoxy-butyloxy)-butan is primarily used as a plasticizer in the production of various polymers, such as polyvinyl chloride (PVC), to enhance their flexibility and durability. It is also employed as a stabilizer in the manufacturing of certain types of plastics and elastomers. Due to its acetoxy groups, 1,4-bis-(4-acetoxy-butyloxy)-butan can undergo hydrolysis, which makes it suitable for applications where controlled degradation is desired. The compound is synthesized through the reaction of butane-1,4-diol with acetic acid and butanol in the presence of a catalyst. It is important to handle this chemical with care, as it may cause irritation to the eyes, skin, and respiratory system, and it is classified as harmful if swallowed.

Check Digit Verification of cas no

The CAS Registry Mumber 3216-77-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,1 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3216-77:
(6*3)+(5*2)+(4*1)+(3*6)+(2*7)+(1*7)=71
71 % 10 = 1
So 3216-77-1 is a valid CAS Registry Number.

Acylative dimerization of tetrahydrofuran catalyzed by rare-earth triflates

Miles, William H.,Ruddy, Daniel A.,Tinorgah, Samira,Geisler, Rebecca L.

, p. 1871 - 1880 (2007/10/03)

Ytterbium, scandium, and lanthanum triflates catalyze the cleavage reactions of cyclic ethers to give various products. Most notable was the acylative cleavage of tetrahydrofuran with acetic anhydride catalyzed by Yb(triflate)3 to give the dime
