780758-19-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 780758-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,8,0,7,5 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 780758-19:
(8*7)+(7*8)+(6*0)+(5*7)+(4*5)+(3*8)+(2*1)+(1*9)=202
202 % 10 = 2
So 780758-19-2 is a valid CAS Registry Number.

A concise formal total synthesis of TMC-95A/B proteasome inhibitors.
Albrecht, Brian K,Williams, Robert M
, p. 197 - 200 (2007/10/03)
[reaction: see text] A formal total synthesis of proteasome inhibitors TMC-95A/B is described. The synthesis features a stereoselective modified Julia olefination and a diastereoselective dihydroxylation to construct the highly oxidized tryptophan residue.
