Check Digit Verification of cas no

The CAS Registry Mumber 1629189-46-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,9,1,8 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1629189-46:
(9*1)+(8*6)+(7*2)+(6*9)+(5*1)+(4*8)+(3*9)+(2*4)+(1*6)=203
203 % 10 = 3
So 1629189-46-3 is a valid CAS Registry Number.

Catalytic enantioselective total synthesis of (-)-pyridovericin

Schmid, Fabian,Bernasconi, Maurizio,Jessen, Henning J.,Pfaltz, Andreas,Gademann, Karl

, p. 864 - 870 (2014/04/03)

The first enantioselective catalytic total synthesis of (-)-pyridovericin is reported. The key steps involve a modified HWE reaction under aqueous conditions and an asymmetric iridium-catalyzed hydrogenation. This resulted in a highly modular and stereoselective approach that delivered the target natural product in high yield and stereoselectivity. Georg Thieme Verlag Stuttgart New York.
