Check Digit Verification of cas no

The CAS Registry Mumber 140685-82-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,6,8 and 5 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 140685-82:
(8*1)+(7*4)+(6*0)+(5*6)+(4*8)+(3*5)+(2*8)+(1*2)=131
131 % 10 = 1
So 140685-82-1 is a valid CAS Registry Number.

Synthesis and aldose reductase inhibitory activities of benzyl-2-oxazolecarbamate analogues

Miyahara,Kasugai,Ohmomo,Tanaka,Tanimoto

, p. 245 - 248 (2007/10/02)

Various analogues of benzyl 5-phenyl-2-oxazolecarbamate (1a) were synthesized, and the structure-activity relationship of these analogues as aldose reductase inhibitor was studied. The carbamate group was necessary for the inhibitory activity. The introduction of an alkyl group at the C-4 position of 1a enhanced the inhibitory activity, however, the N-carboxymethyl group on the carbamate moiety counteracted to a hydrophobic interaction between the alkyl group at the C-4 position and the enzyme molecule.
