Check Digit Verification of cas no

The CAS Registry Mumber 289909-33-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,9,0 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 289909-33:
(8*2)+(7*8)+(6*9)+(5*9)+(4*0)+(3*9)+(2*3)+(1*3)=207
207 % 10 = 7
So 289909-33-7 is a valid CAS Registry Number.

Electrosynthesis of cyclic α-carbonylazo compounds. Chemical stability of the electrogenerated dienophiles and in situ trapping of dienes

Lorans,Hurvois,Moinet

, p. 807 - 813 (2007/10/03)

Dienophilic cyclic α-carbonylazo compounds were prepared electrochemically by oxidation of the corresponding hydrazino compounds using a flow cell fitted with a graphite felt anode in acidic methanol or acetonitrile. The instability of these compounds in methanol was first studied. In situ Diels-Alder additions of these electrogenerated dienophiles and various dienes were performed in relatively good yields in acidic methanol or acetonitrile.
