84423-34-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84423-34-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,4,2 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 84423-34:
(7*8)+(6*4)+(5*4)+(4*2)+(3*3)+(2*3)+(1*4)=127
127 % 10 = 7
So 84423-34-7 is a valid CAS Registry Number.

, p. 565 - 570 (2007/10/02)
Some new policyclic carbazoloquinones, substituted 6H-pyridocarbazoles (V) have been synthesized by the interaction of the Diels-Alder adducts (II), obtained from the addition of cinnamyliden-anils (I) to 4,4-dimethoxyquinone in 1:1 molar ratio, wi
