2-Butyl-2-methyl-propan-1,3-diol, also known as pentaerythritol, is a colorless, crystalline organic compound with the chemical formula C5H12O4. It is a polyol, meaning it contains multiple hydroxyl (-OH) groups, which are present at the 2nd carbon of the molecule. Pentaerythritol is widely used in the production of alkyd resins, which are important components in paints, varnishes, and coatings. It also serves as a cross-linking agent in the synthesis of polyurethanes and as a stabilizer in the production of explosives. Due to its versatile applications, pentaerythritol is a significant chemical in the industrial sector.
The CAS Registry Mumber 3121-83-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,2 and 1 respectively; the second part has 2 digits, 8 and 3 respectively. Calculate Digit Verification of CAS Registry Number 3121-83: (6*3)+(5*1)+(4*2)+(3*1)+(2*8)+(1*3)=53 53 % 10 = 3 So 3121-83-3 is a valid CAS Registry Number.
