Check Digit Verification of cas no

The CAS Registry Mumber 1338575-67-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,5,7 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1338575-67:
(9*1)+(8*3)+(7*3)+(6*8)+(5*5)+(4*7)+(3*5)+(2*6)+(1*7)=189
189 % 10 = 9
So 1338575-67-9 is a valid CAS Registry Number.

Copper-catalyzed iminoiodane-mediated aminolactonization of Olefins: Application to the synthesis of 5,5-disubstituted butyrolactones

Karila, Delphine,Leman, Loic,Dodd, Robert H.

, p. 5830 - 5833 (2011)

A copper(I)-catalyzed reaction of a variety of 4-aryl-pent-4-enoates with nosyliminoiodane generated in situ provides the corresponding 5-aryl-5-nosylamidomethylbutyrolactones. The reaction presumably proceeds via an aziridine intermediate, which could be
