CAS DataBase Reference: Cellulose, acetate butanoate, polymer with 1,3-butanediol, 1,3-diisocyanatomethylbenzene, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol and .alpha.-hydro-.omega.-hydroxypolyoxy(methyl-1,2-ethanediyl)(CAS DataBase Reference)
NIST Chemistry Reference: Cellulose, acetate butanoate, polymer with 1,3-butanediol, 1,3-diisocyanatomethylbenzene, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol and .alpha.-hydro-.omega.-hydroxypolyoxy(methyl-1,2-ethanediyl)(68479-66-3)
EPA Substance Registry System: Cellulose, acetate butanoate, polymer with 1,3-butanediol, 1,3-diisocyanatomethylbenzene, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol and .alpha.-hydro-.omega.-hydroxypolyoxy(methyl-1,2-ethanediyl)(68479-66-3)
The CAS Registry Mumber 68479-66-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,4,7 and 9 respectively; the second part has 2 digits, 6 and 6 respectively. Calculate Digit Verification of CAS Registry Number 68479-66: (7*6)+(6*8)+(5*4)+(4*7)+(3*9)+(2*6)+(1*6)=183 183 % 10 = 3 So 68479-66-3 is a valid CAS Registry Number.
