1428243-89-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1428243-89-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,2,4 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1428243-89:
(9*1)+(8*4)+(7*2)+(6*8)+(5*2)+(4*4)+(3*3)+(2*8)+(1*9)=163
163 % 10 = 3
So 1428243-89-3 is a valid CAS Registry Number.

, p. 11824 - 11826 (2013/01/15)
To the core: The first total synthesis of (-)-lycoposerramine-S has been accomplished in 14 steps. The synthesis features the facile construction of the tetracyclic core through an intramolecular 1,3-dipolar cycloaddition of an azomethine ylide, with unex
