1227951-89-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1227951-89-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,7,9,5 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1227951-89:
(9*1)+(8*2)+(7*2)+(6*7)+(5*9)+(4*5)+(3*1)+(2*8)+(1*9)=174
174 % 10 = 4
So 1227951-89-4 is a valid CAS Registry Number.

Synthesis of bipyrazole and 1,3,4-thiadiazole derivatives
Dawood, Kamal M.,Ragab, Eman A.,Farag, Ahmad M.
experimental part, p. 630 - 634 (2011/02/28)
New hydrazonoyl bromides reacted with several C-nucleophiles to give the corresponding bipyrazoles. Treatment of 3-cyanoacetylpyrazole derivatives with phenyl isothiocyanate in potassium hydroxide followed by hydrazonoyl bromides gave the corresponding py
