92989-84-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92989-84-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,9,8 and 9 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 92989-84:
(7*9)+(6*2)+(5*9)+(4*8)+(3*9)+(2*8)+(1*4)=199
199 % 10 = 9
So 92989-84-9 is a valid CAS Registry Number.

REARRANGEMENT OF α-ACYLOXYACETATES INTO 2-HYDROXY-3-KETOESTERS
Lee, S. D.,Chan, T. H.,Kwon, K. S.
, p. 3399 - 3402 (2007/10/02)
α-Acyloxyacetates rearrange under LDA conditions to give 2-hydroxy-3-ketoesters.The corresponding trimethylsilyl- or acetyl derivatives can be obtained by quenching the reaction mixture with Me3SiCl or Ac2O.
