78837-35-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 78837-35-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,8,3 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 78837-35:
(7*7)+(6*8)+(5*8)+(4*3)+(3*7)+(2*3)+(1*5)=181
181 % 10 = 1
So 78837-35-1 is a valid CAS Registry Number.

Synthesis of Adamantane Derivatives. 54. Synthesis of Novel 4-Azahomoadamantano-Fused Heterocycles via Hydrocyanation of 4-Azahomoadamant-3-ene

Sasaki, Tadashi,Eguchi, Shoji,Okano, Takashi

, p. 4474 - 4477 (1981)

Photolysis of 1-azidoadamantane (1) in an aqueous NaCN-n-hexane two-phase system with Adogen 464 as a phase-transfer catalyst gave 3-cyano-4-azahomoadamantane (3), a hydrocyanation product of 4-azahomoadamant-3-ene (2).AlCl3-catalyzed decomposition of 1 in the presence of trimethylsilyl cyanide also afforded 3. 3 gave the corresponding amino acid 6 and its ester 7. 4-Azahomoadamantano-fused hydantoin, iminohydantoin, iminothiohydantoin, and thiohydantoin, 12-17, were readily prepared by the reactions of 3 with appropriate isocyanates and isothiocyanates.The reactions of 3 with dimethyl acetylenedicarboxylate, methyl vinyl ketone, and diketene afforded the corresponding iminopyrroline (20), aminopyrroline (23), and aminopyrrolinone (26).Acetylation of 3 gave N-acetylamino derivative 27, which was converted to Δ2-oxazolinium perchlorate 30 via N-acetylamino acid 29.
