Synthesis
2-Propenoic acid, 2-methyl-, methyl ester, polymer with ethenylbenzene and 2-propenoic acid is prepared by introducing hydrophilic groups of carboxyl and hydroxyl groups using methyl methacrylate and butyl acrylate as the main monomers and benzoyl peroxide as the initiator.
Check Digit Verification of cas no
The CAS Registry Mumber 25767-39-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,7,6 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 25767-39:
(7*2)+(6*5)+(5*7)+(4*6)+(3*7)+(2*3)+(1*9)=139
139 % 10 = 9
So 25767-39-9 is a valid CAS Registry Number.
