81903-08-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81903-08-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,0 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 81903-08:
(7*8)+(6*1)+(5*9)+(4*0)+(3*3)+(2*0)+(1*8)=124
124 % 10 = 4
So 81903-08-4 is a valid CAS Registry Number.

SYNTHESIS OF SULFONATED 1,2-DICYANOBENZENES

Negrimovsky, V. M.,Derkacheva, V. M.,Luk'yanets, E. A.,Weitemeyer, A.,Woehrle, D.,Schneider, G.

, p. 161 - 168 (2007/10/03)

Employing the corresponding halogen or amino (via the diazonium salts) substituted 1,2-dicyanobenzenes as starting materials 2,3- and 3,4-dicyanobenzenesulfonic acids (3) and (4) are synthesized.Several intermediates useful for the preparation of the sulfonic acids (3) and (4) are also obtained: 3- and 4-mercapto-1,2-dicyanobenzenes (5), (16), 2,3- and 3,4-dicyanobenzenesulfonyl chlorides (10), (11), bis(2,3-dicyanophenyl)- and bis(3,4-dicyanophenyl)-disulfides (14), (15), and several sulfonamides (17)-(24) (from the sulfochlorides (10), (11).In addition, the synthesis of 4-(4-phonoxy-1,2-dicarbonitrile)benzenesulfonic acid (26) is described. Key words: Dicyanobenzenesulfonic acids, 1,2-dicyanobenzene substituted, phthalonitrile substituted.
