2,2-difluoro-ethane-1,1-diol, also known as hydrofluorocarbon-338 (HFC-338), is a colorless, odorless, and non-toxic liquid chemical compound with the molecular formula C2H4F2O2. It is a derivative of ethane, where two hydrogen atoms are replaced by fluorine atoms, and both terminal carbon atoms are connected to hydroxyl groups. 2,2-difluoro-ethane-1,1-diol is primarily used as a refrigerant, blowing agent, and heat transfer medium, offering a lower global warming potential compared to traditional chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). Due to its environmental benefits and safety profile, HFC-338 is gaining popularity as a more sustainable alternative in various industrial applications.

Check Digit Verification of cas no

The CAS Registry Mumber 431-12-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,3 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 431-12:
(5*4)+(4*3)+(3*1)+(2*1)+(1*2)=39
39 % 10 = 9
So 431-12-9 is a valid CAS Registry Number.
