79220-58-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79220-58-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,2,2 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 79220-58:
(7*7)+(6*9)+(5*2)+(4*2)+(3*0)+(2*5)+(1*8)=139
139 % 10 = 9
So 79220-58-9 is a valid CAS Registry Number.

Cyclization of Isothiosemicarbazones. IV. Synthesis of the Triazolopyrimidine Ring System
Yamazaki, Chiji
, p. 1767 - 1772 (2007/10/02)
Condensation of isothiosemicarbazones with ethoxymethylenemalononitrile gave 2,3-dihydrotriazolopyrimidines in moderate to high yields.The 2,3-dihydro compounds were readily oxidized in dimethyl sulfoxide to give the corresponding tri
