19846-89-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19846-89-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,4 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 19846-89:
(7*1)+(6*9)+(5*8)+(4*4)+(3*6)+(2*8)+(1*9)=160
160 % 10 = 0
So 19846-89-0 is a valid CAS Registry Number.

BISPYRAZOLEPYRAZINES AS SELF-CONDENSATION PRODUCTS FROM 4,5-DIAMINOPYRAZOLES
Orlov, V. D.,Kiroga, Kh.,Kolos, N. N.
, p. 1008 - 1011 (2007/10/02)
Bispyrazolopyrazines have been obtained by self-condensation of 4,5-diaminopyrazoles and their structure confirmed by independent synthesis.The spectral data for these compounds is discussed.
