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.

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.
