Check Digit Verification of cas no
The CAS Registry Mumber 86936-87-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,9,3 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 86936-87:
(7*8)+(6*6)+(5*9)+(4*3)+(3*6)+(2*8)+(1*7)=190
190 % 10 = 0
So 86936-87-0 is a valid CAS Registry Number.

Ultraviolet light absorbing compounds having two different chromophors in the same molecule, particularly the benzotriazole chromophor and either the dihydroxybenzophenone or dihydroxyacetophenone chromophor; specifically, the two compounds 3,5-[di(2H-benzotriazole-2-yl)]-2,4-dihydroxyacetophenone and 3,5-[di(2H-benzotriazole-2-yl)]2,4-dihydroxybenzophenone.

Eight benzotriazoles and (4-methoxy)benzotriazoles, mono- or di-substituted derivatives of 2,4-dihydroxyaceto(or benzo)phenone were synthesized by azo coupling of (4-methoxy)2-nitrobenzenediazonium chloride with 2,4-dihydroxyaceto(or benzo)phenone followed by reductive cyclization.Pure monosubstituted compounds were very difficult to prepare.Careful selection of the pH for the azo coupling and selection of the proper reagents for the reductive cyclization were essential.All compounds were characterized by their ultraviolet, infrared, 1H and 13C NMR spectra and theirelemental analysis.These compounds have both the 2(2-hydroxyphenyl)2H-benzotriazole unit and a 2-hydroxyaceto(or benzo)phenone unit in the same molecule and are effective and useful ultraviolet absorbers. - Keywords: Functional polymers; 2(2-Hydroxyphenyl)2H-benzotriazoles; 2-Hydroxyphenylaceto(benzo)phenones; Azo coupling; Reductive cyclization; Ultraviolet stabilizers
