81496-48-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81496-48-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,9 and 6 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 81496-48:
(7*8)+(6*1)+(5*4)+(4*9)+(3*6)+(2*4)+(1*8)=152
152 % 10 = 2
So 81496-48-2 is a valid CAS Registry Number.

Asymmetric addition to chiral aromatic and unsaturated oxazolines using a novel chiral auxillary

Meyers,Schmidt,McKennon

, p. 250 - 262 (2007/10/02)

By utilizing S-serine, both enantiomers of the reduced methoxyamino alcohol (12) were efficiently prepared. The corresponding oxazolines, prepared from these auxiliaries, showed favorable properties toward additions to naphthalenes 22 and cyclohexene, 27.
