161084-29-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161084-29-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,0,8 and 4 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 161084-29:
(8*1)+(7*6)+(6*1)+(5*0)+(4*8)+(3*4)+(2*2)+(1*9)=113
113 % 10 = 3
So 161084-29-3 is a valid CAS Registry Number.

Unusual reactions of secondary amino acids with trifluoroacetic anhydride: A novel access to α-trifluoromethylated acyloins
Kawase, Masami
, p. 149 - 152 (2007/10/02)
A new fragmentation reaction of secondary α-amino acids with trifluoroacetic anhydride under Dakin-West reaction conditions proceeds through oxazolium salt intermediates followed by ring cleavage to form α- trifluoromethylated acyloins in good yields.
