CAS DataBase Reference: 2-Oxepanone, polymer with 1,3-bis(1-isocyanato-1-methylethyl)benzene and 2,2-oxybisethanol, 2-hydroxyethyl acrylate-blocked(CAS DataBase Reference)
NIST Chemistry Reference: 2-Oxepanone, polymer with 1,3-bis(1-isocyanato-1-methylethyl)benzene and 2,2-oxybisethanol, 2-hydroxyethyl acrylate-blocked(121758-78-9)
EPA Substance Registry System: 2-Oxepanone, polymer with 1,3-bis(1-isocyanato-1-methylethyl)benzene and 2,2-oxybisethanol, 2-hydroxyethyl acrylate-blocked(121758-78-9)
The CAS Registry Mumber 121758-78-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,7,5 and 8 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 121758-78: (8*1)+(7*2)+(6*1)+(5*7)+(4*5)+(3*8)+(2*7)+(1*8)=129 129 % 10 = 9 So 121758-78-9 is a valid CAS Registry Number.
