Check Digit Verification of cas no

The CAS Registry Mumber 10181-94-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,1,8 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 10181-94:
(7*1)+(6*0)+(5*1)+(4*8)+(3*1)+(2*9)+(1*4)=69
69 % 10 = 9
So 10181-94-9 is a valid CAS Registry Number.

Products of oxidative coupllng of phenol by horseradish peroxidase

Huixian,Taylor

, p. 1807 - 1817 (1994)

The oxidation and coupling of phenol by horseradish peroxidase in the presence of hydrogen peroxide yielded dimers trimers and higher molecular weight polymers which are mostly insoluble in water, so the products may be removed by centrifugation. However we discovered some products, such as dimers o,o'-biphenol, p,p'-biphenol, o,p'-biphenol, o-phenoxyphenol and p-phenoxyphenol, even though trimer 4-(4-phenoxyphenoxy)phenol were present in the aqueous phase at a very low concentration.
