Check Digit Verification of cas no

The CAS Registry Mumber 1240049-79-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,0,4 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1240049-79:
(9*1)+(8*2)+(7*4)+(6*0)+(5*0)+(4*4)+(3*9)+(2*7)+(1*9)=119
119 % 10 = 9
So 1240049-79-9 is a valid CAS Registry Number.

Allylation of nitrosobenzene with pinacol allylboronates. A regioselective complement to peroxide oxidation

Kyne, Robert E.,Ryan, Michael C.,Kliman, Laura T.,Morken, James P.

scheme or table, p. 3796 - 3799 (2010/10/21)

Addition of nitrosobenzene to pinacol allylboronates leads to oxidation of the organoboron with concomitant rearrangement of the substrate alkene. This reaction appears to proceed by allylboration of the nitroso group in analogy to carbonyl and imine allylation reactions. Remarkably, the N-O bond is cleaved during the reaction such that simple alcohols are the final reaction product.
