98931-10-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98931-10-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,9,3 and 1 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 98931-10:
(7*9)+(6*8)+(5*9)+(4*3)+(3*1)+(2*1)+(1*0)=173
173 % 10 = 3
So 98931-10-3 is a valid CAS Registry Number.

Partial syntheses of new ergoline derivatives from clavine alkaloids, V: Festuclavines mono- and disubstituted at N-1 and N-6
Eichberg,Eich
, p. 621 - 624 (2007/10/02)
Festuclavine (1) 6-cyano-6-nor-1, (3) 6-nor-1 (5) and 6-allyl-6-nor-1 (7) were converted to their 1-allyl- and 1-propyl derivatives with potassium and the corresponding iodide in ammonia. The preparation of 7 from 5 is described.
