Check Digit Verification of cas no

The CAS Registry Mumber 155836-79-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,8,3 and 6 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 155836-79:
(8*1)+(7*5)+(6*5)+(5*8)+(4*3)+(3*6)+(2*7)+(1*9)=166
166 % 10 = 6
So 155836-79-6 is a valid CAS Registry Number.

Enantioconvergent synthesis of (-)-(2R,5S)-1-allyl-2,5-dimethylpiperazine, an intermediate to δ-opioid receptor ligands

Janetka, James W.,Furness, M. Scott,Zhang, Xiaoyan,Coop, Andrew,Folk, John E.,Mattson, Mariena V.,Jacobson, Arthur E.,Rice, Kenner C.

, p. 3976 - 3980 (2007/10/03)

A convenient, high-yield enantioconvergent synthesis of (-)-1-allyl-(2S,5R)-dimethylpiperazine from trans-2,5-dimethylpiperazine has been developed. This compound is an important intermediate in the synthesis of Δ-opioid receptor ligands. The process allows for the laboratory preparation of 100 g quantities of this enantiomerically pure diamine without chromatography. The key steps in the sequence were an efficient optical resolution using relatively inexpensive resolving agents, followed by interconversion of the unwanted (+)-enantiomer into the desired (-)-enantiomer.
