Check Digit Verification of cas no

The CAS Registry Mumber 1332456-48-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,2,4,5 and 6 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1332456-48:
(9*1)+(8*3)+(7*3)+(6*2)+(5*4)+(4*5)+(3*6)+(2*4)+(1*8)=140
140 % 10 = 0
So 1332456-48-0 is a valid CAS Registry Number.

PBu3-mediated vinylogous wittig reaction of α-methyl allenoates with aldehydes and mechanistic investigations

Xu, Silong,Chen, Rongshun,He, Zhengjie

experimental part, p. 7528 - 7538 (2011/11/29)

A highly stereoselective PBu3-mediated vinylogous Wittig olefination between α-methyl allenoates and a variety of aldehydes is presented as the first example of a practical and synthetically useful vinylogous Wittig reaction. Mechanistic experiments including deuterium-labeling, intermediate entrapment, and NMR monitoring have been deliberately conducted. On the basis of mechanistic investigations, a reliable mechanism for the vinylogous Wittig reaction is proposed, which features a water/phosphine-coassisted allylic phosphorus ylide 1,3-rearrangement pathway, rather than previous retro-Diels-Alder ones. It is noteworthy that mechanistic findings in this work also provide supportive evidence for typical mechanisms of important phosphine-mediated reactions of allenoates.
