85093-49-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85093-49-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,0,9 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 85093-49:
(7*8)+(6*5)+(5*0)+(4*9)+(3*3)+(2*4)+(1*9)=148
148 % 10 = 8
So 85093-49-8 is a valid CAS Registry Number.

HYDRAZONES OF PHTHALAZONES. SOME FORMAZANS AND HYDRAZIDINES
Buzykin, B. I.,Bystrykh, N. N.
, p. 953 - 961 (2007/10/02)
In formazans, isolated during the azo coupling of arenediazonium salts with benzylidenehydrazones of 4-chloro-1-phthalazinone, the hydrogen atom is localized at the nitrogen atom of the ring and not in the formazan fragment.These formazans and their analo
