Check Digit Verification of cas no

The CAS Registry Mumber 1338381-10-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,3,8 and 1 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1338381-10:
(9*1)+(8*3)+(7*3)+(6*8)+(5*3)+(4*8)+(3*1)+(2*1)+(1*0)=154
154 % 10 = 4
So 1338381-10-4 is a valid CAS Registry Number.

Fe(OTf)3-Catalyzed Aromatization of Substituted 3-Methyleneindoline and Benzofuran Derivatives: A Selective Route to C-3-Alkylated Indoles and Benzofurans

Kundal, Sandip,Jalal, Swapnadeep,Paul, Kartick,Jana, Umasish

supporting information, p. 5513 - 5517 (2015/09/01)

A simple and convenient approach was developed to the selective synthesis of 3-substituted indoles and benzofurans by the isomerization of 3-methyleneindoline and benzofuran derivatives catalyzed by Fe(OTf)3. The salient features of this method are the easy availability of substrates, high yield, mild reaction conditions, tolerance of a variety of functional groups, and use of an environmentally friendly catalyst. A possible mechanism has also been proposed for the isomerization process.
