Check Digit Verification of cas no

The CAS Registry Mumber 260998-52-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,0,9,9 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 260998-52:
(8*2)+(7*6)+(6*0)+(5*9)+(4*9)+(3*8)+(2*5)+(1*2)=175
175 % 10 = 5
So 260998-52-5 is a valid CAS Registry Number.

Chiral oxime ethers in asymmetric synthesis. Part 4. Asymmetric synthesis of N-protected amines and β-amino acids by the addition of organometallic reagents to ROPHy/SOPHy-derived aldoximes

Hunt, James C. A.,Lloyd, Cephas,Moody, Christopher J.,Slawin, Alexandra M. Z.,Takle, Andrew K.

, p. 3443 - 3454 (2007/10/03)

Addition of organolithium or Grignard reagents to (R)- or (S)-O-(1-phenylbutyl)aldehyde oximes 1 in the presence of boron trifluoride-diethyl ether results in the formation of hydroxylamines 2 in good to excellent diastereoselectivity. Subsequent cleavage of the N-O bond with zinc-acetic acid-ultrasound, and carbamate formation, gives N-protected amines 3 in good enantiomeric purity (77-100% ee). When allylmagnesium bromide was used as the organometallic reagent, the resulting hydroxylamines were converted into β-amino acid derivatives 4 and γ-aminb alcohols 5. The Royal Society of Chemistry 1999.
