Check Digit Verification of cas no

The CAS Registry Mumber 1340542-31-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,0,5,4 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1340542-31:
(9*1)+(8*3)+(7*4)+(6*0)+(5*5)+(4*4)+(3*2)+(2*3)+(1*1)=115
115 % 10 = 5
So 1340542-31-5 is a valid CAS Registry Number.

Total synthesis of haminol A: An analysis of vinylpyridine metathesis reactivity

Storvick, Jennifer M.,Ankoudinova, Evgenia,King, Brianne R.,Van Epps, Heather,O'Neil, Gregory W.

, p. 5858 - 5861 (2011)

The total synthesis of haminol A has been completed featuring a masked-alkene metathesis reaction followed by bis-acyloxysulfone elimination to install the 1,3,8-triene subunit. During the course of our synthesis, the metathesis reactivity of 3-vinylpyridine was evaluated and our data suggest the rapid formation of a ruthenium pyridylalkylidene that no longer participates in productive metathesis. A chemotaxis assay using Caenorhabditis elegans demonstrated that haminol A produced an avoidance response from this organism.
