Check Digit Verification of cas no

The CAS Registry Mumber 1589544-61-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,8,9,5,4 and 4 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1589544-61:
(9*1)+(8*5)+(7*8)+(6*9)+(5*5)+(4*4)+(3*4)+(2*6)+(1*1)=225
225 % 10 = 5
So 1589544-61-5 is a valid CAS Registry Number.

Pyrroles versus cyclic nitrones: Catalyst-controlled divergent cyclization of N-(2-perfluoroalkyl-3-alkynyl) hydroxylamines

Zeng, Qin,Zhang, Li,Yang, Jieru,Xu, Bing,Xiao, Yuanjing,Zhang, Junliang

, p. 4203 - 4206 (2014/04/17)

The IPrAuNTf2/HNTf2 co-catalyzed cyclization of N-(2-perfluoroalkyl-3-alkynyl) hydroxylamines produces pyrroles in moderate to excellent yield, whereas the AgOTf-catalyzed reaction affords cyclic nitrones in high yields. the Partner
