57121-52-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 57121-52-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,1,2 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 57121-52:
(7*5)+(6*7)+(5*1)+(4*2)+(3*1)+(2*5)+(1*2)=105
105 % 10 = 5
So 57121-52-5 is a valid CAS Registry Number.

Miyashita, Akira,Iijima, Chihoko,Higashino, Takeo,Matsuda, Hideaki

, p. 1309 - 1314 (2007/10/02)

Reaction of 5-amino-1-phenyl-1H-pyrazole-4-carboxamide (4) with the esters (3a-h) in the presence of sodium ethoxide in ethanol gave 1-phenyl-1H-pyrazolopyrimidin-4(5H)-one (1a) and its 6-substituted derivatives (1b-h).Similar treatment of 5-amino-1-methyl-1H-pyrazole-4-carboxamide (5) with 3a-h gave the 1-methyl-1H-pyrazolopyrimidin-4(5H)-ones (2a-h).
