519-13-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 519-13-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 519-13:
(5*5)+(4*1)+(3*9)+(2*1)+(1*3)=61
61 % 10 = 1
So 519-13-1 is a valid CAS Registry Number.

Fructosylation of ergot alkaloids by submerged cultures of Claviceps purpurea inhibited in alkaloid production
Kren, V.,Svatos, A.,Valsar, T.,Havlicek, V.,Sedmera, P.,et al.
, p. 652 - 659 (2007/10/02)
Lysergol β-O-D-fructoside and 9,10-dihydrolysergol β-O-D-fructoside were prepared from their respective aglycones by transfructosylation using submerged cultures of Claviceps purpurea inhibited in ergot alkaloid production by 5-fluorotryptophan.The same culture also oxidizes lysergol to penniclavine.
