Check Digit Verification of cas no

The CAS Registry Mumber 176237-60-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,2,3 and 7 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 176237-60:
(8*1)+(7*7)+(6*6)+(5*2)+(4*3)+(3*7)+(2*6)+(1*0)=148
148 % 10 = 8
So 176237-60-8 is a valid CAS Registry Number.

Mononitroalkylations of butane-2,3-dione

Pitacco, Giuliana,Pizzioli, Alessandro,Valentin, Ennio

, p. 242 - 248 (2007/10/03)

The morpholino enamine of monoprotected butane-2,3-dione reacts with cyclic and acyclic conjugated nitroalkenes in a Michael-type reaction to yield nitro-substituted α-diketones, after acidic hydrolysis of the mononitroalkylated enamine adducts. Cyclopentanone, hexahydro-1H-pentalen-2-one and octahydro-2H-inden-2-one derivatives are readily obtained by base-catalyzed intramolecular nitroaldol reaction of the acyclic hydrolysis products.
