Check Digit Verification of cas no
The CAS Registry Mumber 122430-79-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,4,3 and 0 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 122430-79:
(8*1)+(7*2)+(6*2)+(5*4)+(4*3)+(3*0)+(2*7)+(1*9)=89
89 % 10 = 9
So 122430-79-9 is a valid CAS Registry Number.

Synthesis of benzotriazole monomer
-
Page/Page column 19, (2010/12/26)
The synthesis of benzotriazole monomers and the use of the benzotriazole monomers and one or more other monomers to prepare ultraviolet (UV) light absorbing polymer compositions. The synthetic methods described in this application provide a significant improvement over the previous methods used to prepare benzotriazole monomers.
