199277-73-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 199277-73-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,2,7 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 199277-73:
(8*1)+(7*9)+(6*9)+(5*2)+(4*7)+(3*7)+(2*7)+(1*3)=201
201 % 10 = 1
So 199277-73-1 is a valid CAS Registry Number.

Chiral oxazolinylpyridines as ligands for enantioselective palladium catalysed allylic substitution
Chelucci, Giorgio,Medici, Serenella,Saba, Antonio
, p. 3183 - 3184 (1997)
Chiral oxazolinylpyridines were prepared and assessed in the enantioselective palladium catalysed allylic substitution of 1,3-diphenylprop-2-enyl acetate with dimethyl malonate. Enantioselectivity up to 91% was obtained.
