653568-39-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 653568-39-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,3,5,6 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 653568-39:
(8*6)+(7*5)+(6*3)+(5*5)+(4*6)+(3*8)+(2*3)+(1*9)=189
189 % 10 = 9
So 653568-39-9 is a valid CAS Registry Number.

A Formal Synthesis of (-)-Mycalamide A
Trost, Barry M.,Yang, Hanbiao,Probst, Gary D.
, p. 48 - 49 (2007/10/03)
Novel strategies are developed for an efficient formal synthesis of (-)-mycalamide A. The left-hand side (-)-7-benzoylpederic acid is synthesized from (2S,3S)-2,3-epoxybutane. The key features include a highly regioselective Ru-catalyzed alkene-alkyne cou
