Check Digit Verification of cas no

The CAS Registry Mumber 1240520-80-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,5,2 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1240520-80:
(9*1)+(8*2)+(7*4)+(6*0)+(5*5)+(4*2)+(3*0)+(2*8)+(1*0)=102
102 % 10 = 2
So 1240520-80-2 is a valid CAS Registry Number.

Asymmetric synthesis of functionalized, monocyclic chlorocyclobutenes

Darses, Benjamin,Greene, Andrew E.,Poisson, Jean-Francois

supporting information; experimental part, p. 3994 - 3997 (2010/11/03)

Figure presented. The selective synthesis of a variety of stereopure monocyclic chlorocyclobutenes is described. These derivatives could be coupled with Grignard reagents; two dienes from coupling with vinylmagnesium bromide reacted smoothly with maleic anhydride to yield illudol-related [4 + 2] cycloadducts.
