Check Digit Verification of cas no

The CAS Registry Mumber 80376-94-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,3,7 and 6 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 80376-94:
(7*8)+(6*0)+(5*3)+(4*7)+(3*6)+(2*9)+(1*4)=139
139 % 10 = 9
So 80376-94-9 is a valid CAS Registry Number.

α-Amino Carbanions. Preparation, Metalation, and Alkylation of Enamidines. Synthesis of Piperidine and Pyrrolidine Natural Products and Homologation of Carbonyl Compounds

Meyers, A. I.,Edwards, Philip D.,Bailey, Thomas R.,Jagdmann, G. Erik

, p. 1019 - 1026 (2007/10/02)

Saturated heterocycles, as their tert-butylformamidines, may be transformed into enamidines, by metalation-selenation-elimination.These enamidines are valuable precursors to 2-substituted, 2,4-disubstituted, and 2,4,6-trisubstituted pyrrolidines, piperidines, and perhydroazepines, prepared in a regiospecific manner.The method is demonstrated by the synthsesis of selenopsin A and the red fire ant venom.The use of acyclic enamidines is displayed as a homologation reagent which converts carbonyl compounds to higher alkyl derivatives.
