68400-67-9 Usage
General Description
The chemical "1,3-Butanediol, polymer with .alpha.-butyl-.omega.-hydroxypolyoxy(methyl-1,2-ethanediyl) and 1,3-diisocyanatomethylbenzene" is a polymer substance that consists of 1,3-butanediol, alpha-butyl-omega-hydroxypolyoxy(methyl-1,2-ethanediyl), and 1,3-diisocyanatomethylbenzene. 1,3-Butanediol is a colorless, viscous liquid used in the production of various polymers and as a solvent in organic synthesis, while 1,3-diisocyanatomethylbenzene is a chemical used in the production of polyurethane foams and elastomers. When combined in a polymer, these chemicals create a material with various applications in industries such as construction, automotive, and adhesives, due to its strength, flexibility, and insulating properties. However, exposure to this substance may pose risks to human health and the environment, and appropriate safety measures should be taken during its handling and use.
Check Digit Verification of cas no
The CAS Registry Mumber 68400-67-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,4,0 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 68400-67:
(7*6)+(6*8)+(5*4)+(4*0)+(3*0)+(2*6)+(1*7)=129
129 % 10 = 9
So 68400-67-9 is a valid CAS Registry Number.
