CAS DataBase Reference: 1,4-Benzenedicarboxylic acid, polymer with 1,4-cyclohexanedicarboxylic acid and 2,2-dimethyl-1,3-propanediol(CAS DataBase Reference)
NIST Chemistry Reference: 1,4-Benzenedicarboxylic acid, polymer with 1,4-cyclohexanedicarboxylic acid and 2,2-dimethyl-1,3-propanediol(33809-21-1)
EPA Substance Registry System: 1,4-Benzenedicarboxylic acid, polymer with 1,4-cyclohexanedicarboxylic acid and 2,2-dimethyl-1,3-propanediol(33809-21-1)
The CAS Registry Mumber 33809-21-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,8,0 and 9 respectively; the second part has 2 digits, 2 and 1 respectively. Calculate Digit Verification of CAS Registry Number 33809-21: (7*3)+(6*3)+(5*8)+(4*0)+(3*9)+(2*2)+(1*1)=111 111 % 10 = 1 So 33809-21-1 is a valid CAS Registry Number.
