CAS DataBase Reference: 1,2-Propanediol, polymer with 2,4-diisocyanato-1-methylbenzene and methyloxirane, Me Et ketone oxime-blocked(CAS DataBase Reference)
NIST Chemistry Reference: 1,2-Propanediol, polymer with 2,4-diisocyanato-1-methylbenzene and methyloxirane, Me Et ketone oxime-blocked(118439-11-5)
EPA Substance Registry System: 1,2-Propanediol, polymer with 2,4-diisocyanato-1-methylbenzene and methyloxirane, Me Et ketone oxime-blocked(118439-11-5)
The CAS Registry Mumber 118439-11-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,4,3 and 9 respectively; the second part has 2 digits, 1 and 1 respectively. Calculate Digit Verification of CAS Registry Number 118439-11: (8*1)+(7*1)+(6*8)+(5*4)+(4*3)+(3*9)+(2*1)+(1*1)=125 125 % 10 = 5 So 118439-11-5 is a valid CAS Registry Number.
