Check Digit Verification of cas no
The CAS Registry Mumber 343335-40-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,3,3,3 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 343335-40:
(8*3)+(7*4)+(6*3)+(5*3)+(4*3)+(3*5)+(2*4)+(1*0)=120
120 % 10 = 0
So 343335-40-0 is a valid CAS Registry Number.

Rh(I)-catalyzed enantioselective hydrogenation of (E)- and (Z)-beta-(acylamino)acrylates using 1,4-bisphosphine ligands under mild conditions.

[reaction: see text] Rh-Me-BDPMI (1a) complex can be an effective catalyst for the hydrogenations of (E)- and (Z)-beta-(acylamino)acrylates, in which the Z-isomers hydrogenated with the same or even higher ee values than the corresponding E-isomers. The conversion yield and enantioselectivity of E- and Z-isomers were largely dependent on the solvent, and thus, the E-isomers were hydrogenated more effectively in CH(2)Cl(2), whereas the Z-isomers were hydrogenated more effectively in polar MeOH solvent.
