(8*1)+(7*5)+(6*3)+(5*4)+(4*3)+(3*9)+(2*5)+(1*2)=132
132 % 10 = 2
So 153439-52-2 is a valid CAS Registry Number.

Nitrosations with hydrazine derivatives. Novel synthesis of arylsulfonyltriazenes by nitrosation of N4-arylsulfonylsemicarbazides

Hanefeld,Hartmann

, p. 672 - 675 (2007/10/02)

N1-disubstituted N4-arenesulfonylsemicarbazides 3 are prepared by hydrazinolysis of the arenesulfonylurethanes 2, which result from arenesulfonamides and chloroformic acid ester. Under nitrosating conditions 3 are mainly transformed into the sulfonyltriazenes 4.
