Check Digit Verification of cas no

The CAS Registry Mumber 1383717-12-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,3,7,1 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1383717-12:
(9*1)+(8*3)+(7*8)+(6*3)+(5*7)+(4*1)+(3*7)+(2*1)+(1*2)=171
171 % 10 = 1
So 1383717-12-1 is a valid CAS Registry Number.

Enantioselective synthesis of a dual orexin receptor antagonist

Mangion, Ian K.,Sherry, Benjamin D.,Yin, Jingjun,Fleitz, Fred J.

, p. 3458 - 3461 (2012/08/08)

A concise, enantioselective synthesis of the potent dual orexin inhibitor suvorexant (1) is reported. Key features of the synthesis include a mild copper-catalyzed amination, a highly chemoselective conjugate addition, and a tandem enantioselective transamination/seven-membered ring annulation. The synthesis requires inexpensive starting materials and only four linear steps for completion.
