Check Digit Verification of cas no

The CAS Registry Mumber 957777-99-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,7,7,7 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 957777-99:
(8*9)+(7*5)+(6*7)+(5*7)+(4*7)+(3*7)+(2*9)+(1*9)=260
260 % 10 = 0
So 957777-99-0 is a valid CAS Registry Number.

Assymetric formal synthesis of (-)-formoterol and (-)-tamsulosin

Kim, Yongeun,Kang, Lae-Sung,Ha, Hyun-Joon,Ko, Seung Whan,Lee, Won Koo

, p. 2243 - 2248 (2008/09/17)

Biologically important (2R)-2-amino-3-phenylpropanes consisted in commercial drugs including (R,R)-formoterol, and (R)-tamsulosin were prepared from chiral (2R)-aziridine-2-carboxylate without any chromatographic separation. Key reactions include regio- and stereoselective ring opening reaction of aziridin-2-yl-phenylmethanol and subsequent cyclization toward enantiopure 4,5-disubastitued oxazolidin-2-ones as synthetic intermediates.
