Check Digit Verification of cas no

The CAS Registry Mumber 55534-76-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,5,3 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 55534-76:
(7*5)+(6*5)+(5*5)+(4*3)+(3*4)+(2*7)+(1*6)=134
134 % 10 = 4
So 55534-76-4 is a valid CAS Registry Number.

Enantioselective Total Synthesis of (+)-Azimine and (+)-Carpaine

Sato, Taro,Aoyagi, Sakae,Kibayashi, Chihiro

, p. 3839 - 3842 (2003)

(Matrix presented) The enantioselective total syntheses of (+)-azimine and (+)-carpaine have been developed, starting with (S)-1,2,4-butanetriol as a single source of chirality. The key common feature in these syntheses involves stereoselective intramolecular hetero-Diels-Alder reaction of an acylnitroso compound. The critical macrocyclic dilactonization of the N-Cbz derivatives of azimic acid and carpamic acid was efficiently achieved by using the Yamguchi macrocyclization conditions.
