90083-42-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90083-42-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,8 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 90083-42:
(7*9)+(6*0)+(5*0)+(4*8)+(3*3)+(2*4)+(1*2)=114
114 % 10 = 4
So 90083-42-4 is a valid CAS Registry Number.

A PRACTICAL ACCESS TO ALLYLIC SULPHONES AND LACTONES FROM ALLYLIC NITRO COMPOUNDS
Barlaam, Bernard,Boivin, Jean,Zard, Samir Z.
, p. 7429 - 7432 (2007/10/02)
Allylic nitro derivatives can be readily solvolysed in aqueous acetic acid to give allylic sulphones in the presence of a sulphinate salt or allylic lactones if the substrate contains a suitably located ester group.
