Check Digit Verification of cas no

The CAS Registry Mumber 1254074-41-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,0,7 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1254074-41:
(9*1)+(8*2)+(7*5)+(6*4)+(5*0)+(4*7)+(3*4)+(2*4)+(1*1)=133
133 % 10 = 3
So 1254074-41-3 is a valid CAS Registry Number.

Palladium-catalyzed allylation of aryl halides with homoallyl alcohols bearing a trisubstituted double bond: Application to chirality transfer from hydroxylated carbon to benzylic one

Wakabayashi, Ryota,Fujino, Daishi,Hayashi, Sayuri,Yorimitsu, Hideki,Oshima, Koichiro

experimental part, p. 4337 - 4343 (2010/08/20)

(Figure presented) A facile route to homoallyl alcohols bearing a trisubstituted double bond has been devised. The palladium-catalyzed reactions of aryl halides with the alcohols thus synthesized result in regiospecific allyl transfer from the alcohols to aryl halides via retro-allylation, providing allylarenes having two substituents at the 1 and 2 positions of the allyl moiety. Optically active homoallyl alcohols transfer their chirality at the hydroxylated carbon to the benzylic carbon of the product.
