Check Digit Verification of cas no
The CAS Registry Mumber 20119-68-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,1 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20119-68:
(7*2)+(6*0)+(5*1)+(4*1)+(3*9)+(2*6)+(1*8)=70
70 % 10 = 0
So 20119-68-0 is a valid CAS Registry Number.

Vermehren, Jan,Hanack, Michael
, p. 331 - 336 (2007/10/02)
N-(1-Chloroethenyl)-N'-tosyldiazenes 5 are potential precursors to obtaine alkyne diazonium salts 6.Their multistep synthesis starts with substituted acetic acids.The aromatic diazenes 5 are crystalline, intensively orange compounds, which melt above 100
