155855-91-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 155855-91-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,8,5 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 155855-91:
(8*1)+(7*5)+(6*5)+(5*8)+(4*5)+(3*5)+(2*9)+(1*1)=167
167 % 10 = 7
So 155855-91-7 is a valid CAS Registry Number.

Photochemistry of a model lignin compound. spin trapping of primary products and properties of an oligomer
Barclay,Cromwell,Hilborn
, p. 35 - 41 (1994)
α-Guaiacoxylacetoveratrone, 1, was selected as a model of a lignin structure component for photolysis and free radical spin trapping studies. The 3,4-dimethoxyphenacyl radical, Ar-COCH2, 2, thermally generated from α-bromoacetoveratrone with tr
