Check Digit Verification of cas no

The CAS Registry Mumber 1111310-87-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,1,1,3,1 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1111310-87:
(9*1)+(8*1)+(7*1)+(6*1)+(5*3)+(4*1)+(3*0)+(2*8)+(1*7)=72
72 % 10 = 2
So 1111310-87-2 is a valid CAS Registry Number.

Synthesis of isoindoles via 1,3-dipolar cycloaddition of α-azido carbonyl compounds onto intramolecular alkenes and their conversion into substituted aromatic hydrocarbons

Tong, Benny Meng Kiat,Hui, Benjamin Wei-Qiang,Chua, Sze Hui,Chiba, Shunsuke

supporting information; experimental part, p. 3552 - 3562 (2011/12/04)

α-Azido carbonyl compounds bearing a 2-alkenylaryl moiety in the α-position are found to be promising precursors in the synthesis of isoindoles via 1,3-dipolar cycloaddition of azides to alkenes. Applications of these isoindoles in the preparation of 1,2,3,4-tetrasubstituted naphthalene and 9,10-disubstituted anthracene derivatives were developed via [4+2]-cycloaddition reactions of isoindoles with dimethyl acetylenedicarboxylate and benzynes, respectively, followed by deaminative aromatization.
