CAS DataBase Reference: 2-Oxepanone, polymer with 1,4-butanediol, .alpha.-hydro-.omega.-hydroxypoly(oxy-1,4-butanediyl) and 1,1-methylenebis4-isocyanatobenzene(CAS DataBase Reference)
NIST Chemistry Reference: 2-Oxepanone, polymer with 1,4-butanediol, .alpha.-hydro-.omega.-hydroxypoly(oxy-1,4-butanediyl) and 1,1-methylenebis4-isocyanatobenzene(77243-85-7)
EPA Substance Registry System: 2-Oxepanone, polymer with 1,4-butanediol, .alpha.-hydro-.omega.-hydroxypoly(oxy-1,4-butanediyl) and 1,1-methylenebis4-isocyanatobenzene(77243-85-7)
The CAS Registry Mumber 77243-85-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,4 and 3 respectively; the second part has 2 digits, 8 and 5 respectively. Calculate Digit Verification of CAS Registry Number 77243-85: (7*7)+(6*7)+(5*2)+(4*4)+(3*3)+(2*8)+(1*5)=147 147 % 10 = 7 So 77243-85-7 is a valid CAS Registry Number.
