121193-19-9 Usage
General Description
2H-Azepin-2-one, hexahydro-, polymer with 1,3-diisocyanatomethylbenzene and 2-ethyl-2-(hydroxymethyl)-1,3-propanediol is a complex chemical substance typically used in the industrial sector for manufacturing processes. This chemical compound involves a polymer, indicating it consists of repeatedly linked subunits. The substance, which demonstrates properties common to polyurethane materials, is synthesized by the polymerization of hexahydro-2H-azepin-2-one with 1,3-diisocyanatomethylbenzene and the alcohol, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, the former of which is commonly referred to as "isocyanate" and the latter as "trimethylolpropane". Appropriate precautions should be taken due to probable risks associated with occupational exposure.
Check Digit Verification of cas no
The CAS Registry Mumber 121193-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,1,9 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 121193-19:
(8*1)+(7*2)+(6*1)+(5*1)+(4*9)+(3*3)+(2*1)+(1*9)=89
89 % 10 = 9
So 121193-19-9 is a valid CAS Registry Number.
