223379-71-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 223379-71-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,3,7 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 223379-71:
(8*2)+(7*2)+(6*3)+(5*3)+(4*7)+(3*9)+(2*7)+(1*1)=133
133 % 10 = 3
So 223379-71-3 is a valid CAS Registry Number.

Iminophoshorane-mediated synthesis of the alkaloid cryptotackieine
Molina,Fresneda,Delgado
, p. 326 - 329 (2007/10/03)
A new synthesis of the alkaloid cryptotackieine based on the stepwise formation of the pyridine and indole ring is described. The key step, formation of the appropriate 3-arylquinoline, involves a Staudinger/aza- Wittig/electrocyclic ring-closure process.
