The CAS Registry Mumber 900187-89-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,0,1,8 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 900187-89:
(8*9)+(7*0)+(6*0)+(5*1)+(4*8)+(3*7)+(2*8)+(1*9)=155
155 % 10 = 5
So 900187-89-5 is a valid CAS Registry Number.

Oxazolidinones and 2,5-Dihydrofurans via Zinc-Catalyzed Regioselective Allenylation Reactions of l -α-Amino Aldehydes

Zamani, Farzad,Pyne, Stephen G.,Hyland, Christopher J. T.

, p. 6819 - 6830 (2017/07/17)

The simultaneous control of diastereoselectivity and regioselectivity in Zn-catalyzed allenylation reactions of N-protected l-α-amino aldehydes is reported. A reversal in diastereoselectivity could be realized by variation of the α-amino aldehyde protecti
