Check Digit Verification of cas no

The CAS Registry Mumber 1334174-52-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,1,7 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1334174-52:
(9*1)+(8*3)+(7*3)+(6*4)+(5*1)+(4*7)+(3*4)+(2*5)+(1*2)=135
135 % 10 = 5
So 1334174-52-5 is a valid CAS Registry Number.

Double diastereocontrol in bifunctional thiourea organocatalysis: Iterative Michael-Michael-Henry sequence regulated by the configuration of chiral catalysts

Varga, Szilard,Jakab, Gergely,Drahos, Laszlo,Holczbauer, Tamas,Czugler, Matyas,Soos, Tibor

, p. 5416 - 5419 (2011/12/01)

The importance and reactivity consequences of the double diastereocontrol in noncovalent bifunctional organocatalysis were studied. The results suggest that the bifunctional thioureas can have synthetic limitations in multicomponent domino or autotandem catalysis. Nevertheless, we provided a means to exploit this behavior and used the configuration of the chiral catalyst as a control element in organo-sequential reactions.
