Check Digit Verification of cas no

The CAS Registry Mumber 1431767-88-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,7,6 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1431767-88:
(9*1)+(8*4)+(7*3)+(6*1)+(5*7)+(4*6)+(3*7)+(2*8)+(1*8)=172
172 % 10 = 2
So 1431767-88-2 is a valid CAS Registry Number.

The use of sodium chlorite in the direct synthesis of glycidic amides: Enantiopure synthesis of both enantiomers of norbalasubramide

Fuentes, Lilia,Hernández-Juarez, Mireya,Terán, Joel L.,Quintero, Leticia,Sartillo-Piscil, Fernando

, p. 878 - 882 (2013/05/22)

Recently, the first direct method for preparing 2,3-epoxyamides (glycidic amides) was disclosed. Now in this letter, the enantiopure synthesis of both enantiomers of norbalasubramide featuring this synthetic method is reported. To this end, chiral N-allyltryptamine 12 was prepared and transformed into an inseparable mixture of diastereomeric epoxyamides 13a/13b, which were submitted to intramolecular cyclization with Cu(OTf)2 to afford a separable mixture of eight-membered ring lactams 14a and 14b. Finally, after removal of the protective group and the chiral auxiliary an enantiopure synthesis of the title compounds was completed. Georg Thieme Verlag Stuttgart · New York.
