153444-05-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 153444-05-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,4,4 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 153444-05:
(8*1)+(7*5)+(6*3)+(5*4)+(4*4)+(3*4)+(2*0)+(1*5)=114
114 % 10 = 4
So 153444-05-4 is a valid CAS Registry Number.

Reaction of a lignin model dimer sequentially with chlorine and sodium hydroxide
McKague,Reeve
, p. 573 - 576 (2007/10/03)
Dimer 9, which is representative of diaryl methane structures reported present in residual lignin, was reacted with aqueous chlorine at 50 °C. The major product was identified as the tetrachloroquinone dimer 13 (x = 2, y = 2). Similar reaction of the tetr
