74606-97-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74606-97-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,0 and 6 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74606-97:
(7*7)+(6*4)+(5*6)+(4*0)+(3*6)+(2*9)+(1*7)=146
146 % 10 = 6
So 74606-97-6 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
