99809-06-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99809-06-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,8,0 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 99809-06:
(7*9)+(6*9)+(5*8)+(4*0)+(3*9)+(2*0)+(1*6)=190
190 % 10 = 0
So 99809-06-0 is a valid CAS Registry Number.

Synthesis and Properties of 2-Hydroxy Carbohydroximic Esters
Geffken, Detlef,Schwarz, Gabriele
, p. 45 - 49 (2007/10/02)
Sulfhydrolysis of the glycolimidates 4 affords 2-hydroxy thiocarboxylic O-esters 5, which on treatment with hydroxylamine give 2-hydroxy carboximic esters 3.The (E)/(Z) isomer distribution of 3 depends largely on the substituents at C-2 and can be affecte
