549490-78-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 549490-78-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,9,4,9 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 549490-78:
(8*5)+(7*4)+(6*9)+(5*4)+(4*9)+(3*0)+(2*7)+(1*8)=200
200 % 10 = 0
So 549490-78-0 is a valid CAS Registry Number.

Enantioselective total synthesis of (+)-dibromophakellstatin
Poullennec, Karine G.,Romo, Daniel
, p. 6344 - 6345 (2007/10/03)
The first enantioselective total synthesis of (+)-phakellstatin and (+)-dibromophakellstatin was achieved. Key steps in the synthesis were a desymmetrization of the diketopiperazine (S,S)-cyclo (Pro, Pro) via a diastereoselective acylation, an intramolecu
