408307-27-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 408307-27-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,8,3,0 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 408307-27:
(8*4)+(7*0)+(6*8)+(5*3)+(4*0)+(3*7)+(2*2)+(1*7)=127
127 % 10 = 7
So 408307-27-7 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.
