Check Digit Verification of cas no

The CAS Registry Mumber 1334709-43-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,7,0 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1334709-43:
(9*1)+(8*3)+(7*3)+(6*4)+(5*7)+(4*0)+(3*9)+(2*4)+(1*3)=151
151 % 10 = 1
So 1334709-43-1 is a valid CAS Registry Number.

Double arylation of allyl alcohol via a one-pot heck arylation- isomerization-acylation cascade

Colbon, Paul,Ruan, Jiwu,Purdie, Mark,Mulholland, Keith,Xiao, Jianliang

supporting information; experimental part, p. 5456 - 5459 (2011/12/05)

A one-pot, two-step catalytic protocol has been developed. A regioselective Heck coupling between aryl bromides and allyl alcohol leads to the generation of arylated allyl alcohols that in situ isomerize to give aldehydes, which then undergo an acylation reaction with a second aryl bromide. A variety of aryl bromides can be employed in both the initial Heck reaction and the acylation, providing easy access to a wide variety of substituted dihydrochalcones.
