Check Digit Verification of cas no
The CAS Registry Mumber 144631-09-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,6,3 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 144631-09:
(8*1)+(7*4)+(6*4)+(5*6)+(4*3)+(3*1)+(2*0)+(1*9)=114
114 % 10 = 4
So 144631-09-4 is a valid CAS Registry Number.

Synthesis of isoquinoline alkaloids through a 10-membered lactam obtained by radical macrocyclisation
Lamas, Carlos,Saa, Carlos,Castedo, Luis,Dominguez, Domingo
, p. 5653 - 5654 (2007/10/02)
A new versatile method for the synthesis of isoquinoline alkaloids 3 and 5 is based on transannular cyclisation of a key macrocycle 2b obtained by an intramolecular addition of an aryl radical to a trimethylsilylacetylene.
