133838-65-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133838-65-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,8,3 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 133838-65:
(8*1)+(7*3)+(6*3)+(5*8)+(4*3)+(3*8)+(2*6)+(1*5)=140
140 % 10 = 0
So 133838-65-0 is a valid CAS Registry Number.

Biomimetic syntheses of neurotrophic americanola and isoamericanola by horseradish peroxidase (HRP) catalyzed oxidative coupling
Takahashi, Hironobu,Matsumoto, Keiji,Ueda, Masumi,Miyake, Youko,Fukuyama, Yoshiyasu
, p. 245 - 256 (2007/10/03)
Horseradish peroxidase (HRP) catalyzed oxidative coupling of caffeic acid has yielded novel dimeric compounds (8) and (9) having a 1,4-benzodioxane ring, which have been in turn converted to americanol A (1) and isoamericanol A (2) in a few steps respecti
