Check Digit Verification of cas no

The CAS Registry Mumber 127983-46-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,9,8 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 127983-46:
(8*1)+(7*2)+(6*7)+(5*9)+(4*8)+(3*3)+(2*4)+(1*6)=164
164 % 10 = 4
So 127983-46-4 is a valid CAS Registry Number.

Nitrone Cycloadditions: Synthesis of (+/-)-Andrachamine

Carruthers, William,Coggins, Peter,Weston, John B.

, p. 2323 - 2327 (2007/10/02)

The usefulness of the cycloaddition of alkenes to 2-alkyl-2,3,4,5-tetrahydropyridine oxides for the preparation of trans-2,6-dialkylpiperidines is confirmed by a stereoselective synthesis of (+/-)-andrachamine.Peroxy acid oxidation of 9-oxa-1-azabicyclononanes does not lead regioselectively to the corresponding 2-alkyl-2,3,4,5-tetrahydropyridine oxide, as had previously been claimed.
