151883-03-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 151883-03-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,8,8 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 151883-03:
(8*1)+(7*5)+(6*1)+(5*8)+(4*8)+(3*3)+(2*0)+(1*3)=133
133 % 10 = 3
So 151883-03-3 is a valid CAS Registry Number.

Tandem radical cyclisations: Synthesis of lysergic acid derivatives
Ozlu,Cladingboel,Parsons
, p. 2183 - 2206 (2007/10/02)
A novel free radical cyclisation approach for the synthesis of lysergic acid analogues has been investigated. The homolytic cleavage of carbon- bromine bond, mediated by tri-n-butyltin hydride, led to the development of a method for the construction of 3,
