347894-89-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 347894-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,7,8,9 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 347894-89:
(8*3)+(7*4)+(6*7)+(5*8)+(4*9)+(3*4)+(2*8)+(1*9)=207
207 % 10 = 7
So 347894-89-7 is a valid CAS Registry Number.

Design and synthesis of novel tubular and cage structures based on thiazole-containing macrolactams related to marine cyclopeptides
Pattenden,Thompson
, p. 717 - 718 (2007/10/03)
Tubular and cage structures, i.e. 16 and 18, have been synthesised from modified cyclic peptides following selective cyclotrimerisations of L-ornithine and L-glutamic acid thiazole amino acids under high dilution conditions.
