Check Digit Verification of cas no

The CAS Registry Mumber 121440-73-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,4,4 and 0 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 121440-73:
(8*1)+(7*2)+(6*1)+(5*4)+(4*4)+(3*0)+(2*7)+(1*3)=81
81 % 10 = 1
So 121440-73-1 is a valid CAS Registry Number.

General method for the palladium-catalyzed allylation of aliphatic alcohols

Haight, Anthony R.,Stoner, Eric J.,Peterson, Matthew J.,Grover, Vandana K.

, p. 8092 - 8096 (2007/10/03)

A palladium catalysis-mediated approach to coupling aliphatic alcohols with allyl carbonates has been developed. The method allows for the allylation of primary, secondary, and tertiary alcohols efficiently under mild conditions. Limitations were explored as well as the asymmetric application of the chemistry. Regiochemical and olefin geometry was controlled in the coupling of unsymmetrical allylating agents. Transient allyl carbonates were observed in the coupling, which comprised the trans-carboxylation of the allyl-carbonate with the requisite alcohol.
