Check Digit Verification of cas no
The CAS Registry Mumber 80685-67-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,8 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 80685-67:
(7*8)+(6*0)+(5*6)+(4*8)+(3*5)+(2*6)+(1*7)=152
152 % 10 = 2

SYNTHESIS OF 1-AZIDOANTHRAQUINONES
Gornostaev, L. M.,Sakilidi, V. T.
, p. 1978 - 1981 (2007/10/02)
1-Azidoanthraquinones were synthesized by the reaction of 1-nitroanthraquinones with alkali-metal azides in polar aprotic solvents.The reaction is realized readily for various 1-nitroanthraquinones containing electron-donating and electron-withdrawing sub
