85723-93-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85723-93-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,7,2 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 85723-93:
(7*8)+(6*5)+(5*7)+(4*2)+(3*3)+(2*9)+(1*3)=159
159 % 10 = 9
So 85723-93-9 is a valid CAS Registry Number.

Synthesis of 5-Amino-1,3-dimethylpyrazol-4-yl Aryl Ketones
DeWald, H. A.
, p. 1175 - 1176 (2007/10/02)
A convenient preparation of 5-amino-1,3-dialkylpyrazol-4-yl heterocyclic ketones is reported.They are prepared from the reaction of heterocyclic esters with the di-lithio derivative from N-(4-bromo-1,3-dimethyl-1H-pyrazol-5-yl)benzamide (1).
