Check Digit Verification of cas no

The CAS Registry Mumber 1338045-85-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,0,4 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1338045-85:
(9*1)+(8*3)+(7*3)+(6*8)+(5*0)+(4*4)+(3*5)+(2*8)+(1*5)=154
154 % 10 = 4
So 1338045-85-4 is a valid CAS Registry Number.

Rhodium-catalyzed asymmetric addition of arylboroxines to β-alkoxyacrylate esters

Nishimura, Takahiro,Kasai, Atsuyuki,Nagaosa, Makoto,Hayashi, Tamio

, p. 10488 - 10490 (2011/12/04)

Asymmetric addition of arylboroxines to β-alkoxyacrylate esters proceeded in the presence of a rhodium complex coordinated with a chiral diene ligand to give high yields of β-alkoxy-β-arylcarboxylic acid esters with very high enantioselectivity.
