Check Digit Verification of cas no

The CAS Registry Mumber 1121-33-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,2 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1121-33:
(6*1)+(5*1)+(4*2)+(3*1)+(2*3)+(1*3)=31
31 % 10 = 1
So 1121-33-1 is a valid CAS Registry Number.

Regioselective synthesis of 2,2-dimethylcyclopentanone using 2-pyrrolidone magnesium salt as electrogenerated base

Bonafoux, Dominique,Bordeau, Michel,Biran, Claude,Dunogues, Jacques

, p. 93 - 98 (2007/10/03)

An efficient, direct and regioselective preparation of 2,2-dimethylcyclopentanone, via its enolate precursor regioselectively obtained using the 2-pyrrolidone magnesium salt, a base electrogenerated in DME/HMPA, is reported.

CUPRATE ADDITIONS TO 5-METHOXYCYCLOPENTENONES: A NOVEL STEREOELECTRONIC EFFECT

Smith III, Amos B.,Dunlap, Norma K.,Sulikowski, Gary A.

, p. 439 - 442 (2007/10/02)

Cuprate additions to 5-methoxy-2-cyclopentenone have been found to proceed with moderate to extremely high diastereofacial selectivity, depending upon the specific cuprate and reaction protocol employed.Comparisons with related 5-substitued cyclopentenones suggest that the observed selectivity is not simply steric in nature, but instead reflects a novel stereoelectronic effect.
