Check Digit Verification of cas no

The CAS Registry Mumber 1254219-14-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,2,1 and 9 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1254219-14:
(9*1)+(8*2)+(7*5)+(6*4)+(5*2)+(4*1)+(3*9)+(2*1)+(1*4)=131
131 % 10 = 1
So 1254219-14-1 is a valid CAS Registry Number.

Efficient ring-closing metathesis of alkenyl bromides: The importance of protecting the catalyst during the olefin approach

Gatti, Michele,Drinkel, Emma,Wu, Linglin,Pusterla, Ivano,Gaggia, Fiona,Dorta, Reto

supporting information; experimental part, p. 15179 - 15181 (2010/12/24)

We present the first productive ring-closing metathesis reaction that leads to the construction of cyclic alkenyl bromides. Efficient catalysis employing commercially available Grubbs II catalyst is possible through appropriate modification of the starting bromoalkene moiety.
