Check Digit Verification of cas no

The CAS Registry Mumber 1174637-69-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,4,6,3 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1174637-69:
(9*1)+(8*1)+(7*7)+(6*4)+(5*6)+(4*3)+(3*7)+(2*6)+(1*9)=174
174 % 10 = 4
So 1174637-69-4 is a valid CAS Registry Number.

Chiral cyclic zwitterionic bipyridinium-4-olates for the diastereoselective synthesis of (R,S)- A nd (S,R)-trozamicol

López-González, Ricardo,Zárate, Araceli,Aparicio, David M.,Mendoza, Angel,Gnecco, Dino,Juárez, Jorge R.,Romero-Ceronio, Nancy,Orea, Laura,Terán, Joel L.

, p. 1683 - 1686 (2016/04/04)

A series of new chiral enantiopure cyclic zwitterionic bipyridinium-4-olates compounds were prepared in four steps starting from the corresponding primary chiral amine. With these intermediates, a convenient methodology has been developed for the synthesis of cis-3-piperidinyl-4-hydroxypiperidines. Specifically, the utility of this chiral zwitterionic type intermediate has been demonstrated by the synthesis of (R,S)- A nd (S,R)-trozamicol.
