Check Digit Verification of cas no

The CAS Registry Mumber 1084795-66-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,4,7,9 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1084795-66:
(9*1)+(8*0)+(7*8)+(6*4)+(5*7)+(4*9)+(3*5)+(2*6)+(1*6)=193
193 % 10 = 3
So 1084795-66-3 is a valid CAS Registry Number.

Two-step allylic carbon insertion between ketone carbonyl and α carbons giving α-quaternary α-vinyl ketones

He, Jing-Qian,Shibata, Daisuke,Ohno, Chihaya,Okamoto, Sentaro

, p. 6724 - 6727 (2008)

Ketones 1 were converted to α-quaternary α-vinyl ketones 2 by a two-step formal allylic carbon insertion between ketone carbonyl and α carbons, which involves the reaction of 1 with propargyltitanium reagents, derived from propargyl carbonates 3 and a divalent titanium reagent Ti(O-i-Pr)4/2i-PrMgCl, and the following rearrangement of the resulting α-allenyl alcohols 4 with NBS.
