99698-86-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99698-86-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,6,9 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 99698-86:
(7*9)+(6*9)+(5*6)+(4*9)+(3*8)+(2*8)+(1*6)=229
229 % 10 = 9
So 99698-86-9 is a valid CAS Registry Number.

A SYNTHESIS OF 2-ALKYL-3-FUROIC ACIDS
Tius, Marcus A.,Savariar, Selvaraj
, p. 3635 - 3638 (2007/10/02)
An efficient synthesis of 2-alkyl-3-furoic acids has been developed.Addition of the lithium dianion of 4-oxo-2-phenylthiobutanoic acid ethylene acetal to aldehydes followed by acid-catalyzed cyclization produces furan products in high yield.
