103185-30-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103185-30-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,1,8 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 103185-30:
(8*1)+(7*0)+(6*3)+(5*1)+(4*8)+(3*5)+(2*3)+(1*0)=84
84 % 10 = 4
So 103185-30-4 is a valid CAS Registry Number.

Convergent total syntheses of fluvibactin and vibriobactin using molybdenum(vi) oxide-catalyzed dehydrative cyclization as a key step
Sakakura, Akira,Umemura, Shuhei,Ishihara, Kazuaki
supporting information; experimental part, p. 3561 - 3563 (2009/02/05)
Efficient total syntheses of fluvibactin and vibriobactin have been achieved via molybdenum(vi) oxide-catalyzed dehydrative cyclization, Sb(OEt)3-catalyzed ester-amide transformation, and WSCI and HOAt-promoted dehydrative amide formation. The Royal Society of Chemistry.
