Check Digit Verification of cas no

The CAS Registry Mumber 72326-41-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,3,2 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 72326-41:
(7*7)+(6*2)+(5*3)+(4*2)+(3*6)+(2*4)+(1*1)=111
111 % 10 = 1
So 72326-41-1 is a valid CAS Registry Number.

Synthesis of Multiple-Substituted Pyrroles via Gold(I)-Catalyzed Hydroamination/Cyclization Cascade

Li, Xiangdong,Chen, Ming,Xie, Xin,Sun, Ning,Li, Shi,Liu, Yuanhong

, p. 2984 - 2987 (2015)

A gold-catalyzed cascade hydroamination/cyclization reaction of α-amino ketones with alkynes to form substituted pyrroles has been developed. The method offers several advantages such as high regioselectivity with the tested cases, wide functional group tolerance, and easily accessible starting materials. The synthetic utility of the obtained pyrrole products was demonstrated by their efficient transformations to 2-vinylated pyrroles via gold-catalyzed intermolecular hydroarylation.
