328093-38-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 328093-38-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,8,0,9 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 328093-38:
(8*3)+(7*2)+(6*8)+(5*0)+(4*9)+(3*3)+(2*3)+(1*8)=145
145 % 10 = 5
So 328093-38-5 is a valid CAS Registry Number.

Total synthesis of (-)-spirotryprostatin B and three stereoisomers
Overman, Larry E.,Rosen, Mark D.
, p. 4596 - 4599 (2007/10/03)
Heck cyclization and trapping of the resultant η3-allylpalladium intermediate by a tethered diketopiperazine is the central step in a new stereo controlled route to spirotryprostatin alkaloids. The versatility of this approach is illustrated by
