Check Digit Verification of cas no

The CAS Registry Mumber 1283231-68-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,3,2,3 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1283231-68:
(9*1)+(8*2)+(7*8)+(6*3)+(5*2)+(4*3)+(3*1)+(2*6)+(1*8)=144
144 % 10 = 4
So 1283231-68-4 is a valid CAS Registry Number.

Highly regio- and stereoselective synthesis of alkenylboronic esters by copper-catalyzed boron additions to disubstituted alkynes

Kim, Hye Ryung,Yun, Jaesook

supporting information; experimental part, p. 2943 - 2945 (2011/05/04)

The copper-catalyzed addition of bis(pinacolato)diboron to internal alkynes in the presence of methanol generates alkenylboron compounds with high levels of regio- and stereoselectivities. The catalytic efficiency is increased by using monodentate phosphine ligands, especially P(p-tolyl)3 and a range of internal alkynes was borylated in good yields. The Royal Society of Chemistry.
