Check Digit Verification of cas no

The CAS Registry Mumber 1024-29-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,2 and 4 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1024-29:
(6*1)+(5*0)+(4*2)+(3*4)+(2*2)+(1*9)=39
39 % 10 = 9
So 1024-29-9 is a valid CAS Registry Number.

N-hydroxylamines: Influence of Substituents on the Competitive Migration of Aryl and Phenyl Groups in the Lossen-like Rearrangement of their O-Methanesulphonyl Derivatives

Harger, Martin J. P.,Smith, Adrian

, p. 1787 - 1792 (2007/10/02)

The N-hydroxylamines ArPhP(O)NHOH (4) (Ar=p-XC6H4; X=MeO, Me, Cl, NO2) have been prepared from the corresponding phosphinic chlorides (3) using O-(trimethylsilyl)hydroxylamine and converted into the O-methanesulphonyl derivatives
