Check Digit Verification of cas no

The CAS Registry Mumber 1402079-19-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,2,0,7 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1402079-19:
(9*1)+(8*4)+(7*0)+(6*2)+(5*0)+(4*7)+(3*9)+(2*1)+(1*9)=119
119 % 10 = 9
So 1402079-19-9 is a valid CAS Registry Number.

Quadruple domino organocatalysis: An asymmetric aza-Michael/Michael/ Michael/Aldol reaction sequence leading to tetracyclic indole structures with six stereocenters

Enders, Dieter,Greb, Andreas,Deckers, Kristina,Selig, Philipp,Merkens, Carina

, p. 10226 - 10229 (2012/10/08)

Quadruple domino/Wittig-one pot: An organocatalytic, asymmetric, three-component quadruple cascade, which leads to tetracyclic double-annulated indole derivatives, is described. The domino products were further derivatized by aldehyde olefination under one-pot conditions to obtain complex isoindolo[2, 1-a]indole derivatives bearing six stereogenic centers in a highly stereoselective fashion.
