161745-47-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161745-47-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,7,4 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 161745-47:
(8*1)+(7*6)+(6*1)+(5*7)+(4*4)+(3*5)+(2*4)+(1*7)=137
137 % 10 = 7
So 161745-47-7 is a valid CAS Registry Number.

Synthesis of (R)-(+)-boc-iturinic acid (n-C14) from aspartic acid
Bland
, p. 467 - 477 (1995)
The first enantiospecific synthesis of the n-C14 isomer of iturinic acid, suitably protected for peptide synthesis, is presented. A new method for the synthesis of enantiomerically pure β-amino acids from aspartic acid is used. The key step con
