EPA Substance Registry System: Poly(oxy-1,4-butanediyl), .alpha.-hydro-.omega.-hydroxy-, polymer with 1,3-diisocyanato-2-methylbenzene and 2,4-diisocyanato-1-methylbenzene yanato-2-methylbenzene and 2,4-diisocyanato-1-methylbenzene(64771-77-3)
The CAS Registry Mumber 64771-77-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,7,7 and 1 respectively; the second part has 2 digits, 7 and 7 respectively. Calculate Digit Verification of CAS Registry Number 64771-77: (7*6)+(6*4)+(5*7)+(4*7)+(3*1)+(2*7)+(1*7)=153 153 % 10 = 3 So 64771-77-3 is a valid CAS Registry Number.
