221632-66-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 221632-66-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,6,3 and 2 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 221632-66:
(8*2)+(7*2)+(6*1)+(5*6)+(4*3)+(3*2)+(2*6)+(1*6)=102
102 % 10 = 2
So 221632-66-2 is a valid CAS Registry Number.

Stereocontrolled synthesis of the alkaloid (-)-actinidine
Stepanov,Lozanova,Veselovsky
, p. 2286 - 2291 (2007/10/03)
The alkaloid (-)-actinidine of the iridane series was synthesized using intramolecular [3+2] dipolar cycloaddition of silyl nitronates, generated from (3R/S,6S)-2,6-dimethyl-3-nitro-8-phenylthioocta-1,7E-and -1,7Z-dienes. The key nitro compounds were obtained from (-)-(S)-citronellol.
