193952-41-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 193952-41-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,9,5 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 193952-41:
(8*1)+(7*9)+(6*3)+(5*9)+(4*5)+(3*2)+(2*4)+(1*1)=169
169 % 10 = 9
So 193952-41-9 is a valid CAS Registry Number.

Synthesis of tris-bridged cyclic peptides as an active site mimic of lipase
Uchida,Kato,Achiwa
, p. 1228 - 1230 (2007/10/03)
Tris-bridged cyclic peptides containing serine-histidine and carboxylic acid as an active site of lipase were synthesized. The catalytic activity of the synthetic peptides for the transesterification of 4-nitrophenyl acetate in DMSO was examined.
