19550-73-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19550-73-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,5,5 and 0 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 19550-73:
(7*1)+(6*9)+(5*5)+(4*5)+(3*0)+(2*7)+(1*3)=123
123 % 10 = 3
So 19550-73-3 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.
