82359-57-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82359-57-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,3,5 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 82359-57:
(7*8)+(6*2)+(5*3)+(4*5)+(3*9)+(2*5)+(1*7)=147
147 % 10 = 7
So 82359-57-7 is a valid CAS Registry Number.

Synthesis of ergot alkaloids from tryptophan
Rebek Jr.,Tai,Shue
, p. 1813 - 1819 (2007/10/02)
The first total syntheses of lysergine and setoclavine are described, as well as a new and efficient synthesis of lysergic acid. The starting material for these syntheses is tryptophan, protected as its dihydro, dibenzoyl derivative. This material is dehy
