Check Digit Verification of cas no

The CAS Registry Mumber 1259025-05-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,0,2 and 5 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1259025-05:
(9*1)+(8*2)+(7*5)+(6*9)+(5*0)+(4*2)+(3*5)+(2*0)+(1*5)=142
142 % 10 = 2
So 1259025-05-2 is a valid CAS Registry Number.

N-heterocyclic carbene-catalyzed cross-coupling of aromatic aldehydes with activated alkyl halides

Padmanaban, Mohan,Biju, Akkattu T.,Glorius, Frank

supporting information; experimental part, p. 98 - 101 (2011/03/19)

N-Heterocyclic carbene-catalyzed umpolung of aldehydes followed by their interception with diarylbromomethanes has been reported. This conceptually novel transition-metal-free cross-coupling of aldehydes with alkyl halides works well at low catalyst loadings and under mild reaction conditions leading to the formation of diaryl acetophenone derivatives in good yields. In addition, α-halo ketones and esters can also be used as aldehyde reaction partners.
