Calculate Digit Verification of CAS Registry Number 1255215-28:
(9*1)+(8*2)+(7*5)+(6*5)+(5*2)+(4*1)+(3*5)+(2*2)+(1*8)=131
131 % 10 = 1

supporting information; experimental part, p. 2291 - 2298 (2010/12/20)

The asymmetric synthesis of Maraviroc (UK-427,857), a chemochine receptor 5 (CCR-5) receptor antagonist, based on an expeditious organocatalytic enantioselective assembly of the chiral βamino aldehyde key fragment is presented. The reactions were performed on a gram-scale and allow for the rapid construction of new Maraviroc analogues.
