138680-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138680-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,6,8 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 138680-20:
(8*1)+(7*3)+(6*8)+(5*6)+(4*8)+(3*0)+(2*2)+(1*0)=143
143 % 10 = 3
So 138680-20-3 is a valid CAS Registry Number.

The synthesis and characterization of a pentafluorosulfanylated peptide
Lim, Dong Sung,Lin, Jin-Hong,Welch, John T.
, p. 3946 - 3954 (2012)
The design and synthesis of pentafluorosulfanyl-containing heptad amino acid sequence was described. The three-dimensional conformation of the peptide was investigated by using CYANA (combined assignment and dynamics algorithm for NMR applications) and th
