16105-22-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 16105-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,1,0 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 16105-22:
(7*1)+(6*6)+(5*1)+(4*0)+(3*5)+(2*2)+(1*2)=69
69 % 10 = 9
So 16105-22-9 is a valid CAS Registry Number.

Anderson, Robert M.
, p. 3933 - 3959 (2007/10/02)
1- and 2-Ethanoyl-, propanoyl-, butanoyl- and benzoylindazolin-3-ones have been prepared and the 2-isomers have been shown to exist in two tautomeric forms.Sulphonylation and further acylation of these compounds are described and some rearrangements in the series are discussed.
