27798-98-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 27798-98-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,7,9 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 27798-98:
(7*2)+(6*7)+(5*7)+(4*9)+(3*8)+(2*9)+(1*8)=177
177 % 10 = 7
So 27798-98-7 is a valid CAS Registry Number.

ASYMMETRIC SYNTHESES BASED ON HEXAHYDRO-4,4,7-TRIMETHYL-1,3-BENZOXATHIANS
Eliel, Ernest L.
, p. 73 - 96 (2007/10/02)
Earlier work concerned with a highly stereoselective asymmetric synthesis based on a 1,3-oxathiane as the chiral auxiliary reagent is reviewed and recent applications to the synthesis of the four stereoisomers of malyngolide, of (R)-(+)-γ-caprolactone (a
