875903-56-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 875903-56-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,5,9,0 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 875903-56:
(8*8)+(7*7)+(6*5)+(5*9)+(4*0)+(3*3)+(2*5)+(1*6)=213
213 % 10 = 3
So 875903-56-3 is a valid CAS Registry Number.

, p. 636 - 644 (2007/10/03)
An efficient route to the neocarzinostatin chromophore aglycon has been developed. The present strategy involves a stereoselective intramolecular acetylide-aldehyde cyclization to form the C5-C6 bond, followed by efficient installation of α-epoxide, napht
