334659-88-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 334659-88-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,4,6,5 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 334659-88:
(8*3)+(7*3)+(6*4)+(5*6)+(4*5)+(3*9)+(2*8)+(1*8)=170
170 % 10 = 0
So 334659-88-0 is a valid CAS Registry Number.

Synthesis and stereochemical elucidation of a 14-membered ring phosphonate
Pungente, Michael D.,Weiler, Larry
, p. 643 - 646 (2007/10/03)
We report the synthesis and stereochemical elucidation of a 14-membered ring phosphonate. The key step in the synthesis of the macrolide phosphonate was the cyclization of the acyclic precursor using the Mitsunobu reaction, a mild reaction for the prepara
