137703-75-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137703-75-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,7,0 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 137703-75:
(8*1)+(7*3)+(6*7)+(5*7)+(4*0)+(3*3)+(2*7)+(1*5)=134
134 % 10 = 4
So 137703-75-4 is a valid CAS Registry Number.

First Synthesis of Aminobisabolene
Ichikawa, Yoshiyasu
, p. 1347 - 1350 (2007/10/02)
Two routes for the synthesis of aminobisabolenes were developed.One is the divergent course which completes the first synthesis of the target molecules.Another synthetic route is the biomimetic approach based on the hypothesis of biosynthesis.
