Check Digit Verification of cas no

The CAS Registry Mumber 1184775-81-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,4,7,7 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1184775-81:
(9*1)+(8*1)+(7*8)+(6*4)+(5*7)+(4*7)+(3*5)+(2*8)+(1*1)=192
192 % 10 = 2
So 1184775-81-2 is a valid CAS Registry Number.

Synthesis and characterization of all possible diastereoisomers of alvimopan

Reddy, Beeravalli Ramalinga,Dubey, Manoj Kumar,Ramana Reddy, Ch. Venkata,Bandichhor, Rakeshwar

, p. 963 - 972 (2018/05/28)

Isolation of all possible diastereomers of alvimopan 1 was found to be challenging. In order to perform cut off studies during analytical method development, it was mandatory to synthesize and characterize all the diastereomeric impurities. Here in, our efforts toward the synthesis and isolation of alvimopan (1) diastereomers are discussed.
