342797-09-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 342797-09-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,2,7,9 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 342797-09:
(8*3)+(7*4)+(6*2)+(5*7)+(4*9)+(3*7)+(2*0)+(1*9)=165
165 % 10 = 5
So 342797-09-5 is a valid CAS Registry Number.

A novel enantioselective synthetic route to omuralide analogues with the potential for species selectivity in proteasome inhibition.
Crane,Corey
, p. 1395 - 1397 (2007/10/03)
[reaction in text] The building blocks shown can be combined for an enantioselective construction of the simplified omuralide analogue 4 in nine steps, with the use of (R)-atrolactic acid as a recoverable chiral controller.
