Check Digit Verification of cas no

The CAS Registry Mumber 943443-49-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,3,4,4 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 943443-49:
(8*9)+(7*4)+(6*3)+(5*4)+(4*4)+(3*3)+(2*4)+(1*9)=180
180 % 10 = 0
So 943443-49-0 is a valid CAS Registry Number.

Synthesis of bulky phosphines by rhodium-catalyzed formal [2 + 2 + 2] cycloaddition reactions of tethered diynes with 1-alkynylphosphine sulfides

Kondoh, Azusa,Yorimitsu, Hideki,Oshima, Koichiro

, p. 6996 - 6997 (2008/02/09)

The reaction of tethered diynes with 1-alkynylphosphine sulfides under rhodium catalysis provides the corresponding phosphine sulfides having a bulky aryl group. The following desulfidation yields bulky phosphines that will potentially serve as ligands in
