CAS DataBase Reference: Carbonic acid, polymer with 1,6-hexane-diol, 1,1'-methylenebis[4-isocyanato-benzene] and 2,2'-[1,4-phenylenebis(oxy)bis[ethanol](CAS DataBase Reference)
NIST Chemistry Reference: Carbonic acid, polymer with 1,6-hexane-diol, 1,1'-methylenebis[4-isocyanato-benzene] and 2,2'-[1,4-phenylenebis(oxy)bis[ethanol](89485-74-5)
EPA Substance Registry System: Carbonic acid, polymer with 1,6-hexane-diol, 1,1'-methylenebis[4-isocyanato-benzene] and 2,2'-[1,4-phenylenebis(oxy)bis[ethanol](89485-74-5)
The CAS Registry Mumber 89485-74-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,4,8 and 5 respectively; the second part has 2 digits, 7 and 4 respectively. Calculate Digit Verification of CAS Registry Number 89485-74: (7*8)+(6*9)+(5*4)+(4*8)+(3*5)+(2*7)+(1*4)=195 195 % 10 = 5 So 89485-74-5 is a valid CAS Registry Number.
