1019020-13-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1019020-13-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,9,0,2 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1019020-13:
(9*1)+(8*0)+(7*1)+(6*9)+(5*0)+(4*2)+(3*0)+(2*1)+(1*3)=83
83 % 10 = 3
So 1019020-13-3 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 (1993)
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.
