1371603-73-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1371603-73-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,1,6,0 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1371603-73:
(9*1)+(8*3)+(7*7)+(6*1)+(5*6)+(4*0)+(3*3)+(2*7)+(1*3)=144
144 % 10 = 4
So 1371603-73-4 is a valid CAS Registry Number.

Total synthesis of (-)-goniotrionin
Dias, Luiz C.,Ferreira, Marco A. B.
, p. 4046 - 4062 (2012/06/29)
A stereoselective total synthesis of the reported structure of goniotrionin (4) has been accomplished. The key steps involved the opening of a chiral epoxide, a highly diastereoselective Mukaiyama aerobic oxidative cyclization, a selective 1,2-syn Mukaiyama aldol reaction, and a Noyori reduction.
