Check Digit Verification of cas no
The CAS Registry Mumber 511513-24-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,1,5,1 and 3 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 511513-24:
(8*5)+(7*1)+(6*1)+(5*5)+(4*1)+(3*3)+(2*2)+(1*4)=99
99 % 10 = 9
So 511513-24-9 is a valid CAS Registry Number.

Synthesis of β-tosylethylhydrazine and its use in preparation of N-protected pyrazoles and 5-aminopyrazoles
Dastrup, David M.,Yap, Amy H.,Weinreb, Steven M.,Henry, James R.,Lechleiter, Andrew J.
, p. 901 - 906 (2007/10/03)
β-Tosylethylhydrazine (6) can be prepared efficiently in one step from commercially available p-tolyl vinyl sulfone (7) and hydrazine hydrate. This hydrazine reacts with both 1,3-diketones and conjugated ynones in glacial acetic acid to provide a variety of N-tosylethyl-protected (TSE) pyrazoles in good yields. The TSE group can be removed from the pyrazoles using potassium t-butoxide in THF at -30°C-rt. In addition, hydrazine 6 condenses with β-ketonitriles and β-aminoacrylonitriles to afford 5-aminopyrazoles, which can be deprotected by brief treatment with NaOEt in EtOH/DMSO at 45°C.
