145757-73-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145757-73-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,7,5 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 145757-73:
(8*1)+(7*4)+(6*5)+(5*7)+(4*5)+(3*7)+(2*7)+(1*3)=159
159 % 10 = 9
So 145757-73-9 is a valid CAS Registry Number.

, p. 6995 - 6998 (2007/10/02)
Peptide antibiotic, Leucinostatin D, was synthesized by stepwise elongation method, starting from β-alanine t-butyl ester. Z-octapeptide ester was converted to amide derivative and finally coupled with (4S,E)-4-methylhex-2-enoyl-L-4-methylproline.
