Check Digit Verification of cas no

The CAS Registry Mumber 1190789-25-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,0,7,8 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1190789-25:
(9*1)+(8*1)+(7*9)+(6*0)+(5*7)+(4*8)+(3*9)+(2*2)+(1*5)=183
183 % 10 = 3
So 1190789-25-3 is a valid CAS Registry Number.

Preparation of multisubstituted enamides via rhodium-catalyzed carbozincation and hydrozincation of ynamides

Gourdet, Benoit,Rudkin, Mairi E.,Watts, Ciorsdaidh A.,Hon, Wai Lam

supporting information; experimental part, p. 7849 - 7858 (2010/01/16)

(Chemical Equation Presented) Rhodium-catalyzed carbozincation of ynamides using diorganozinc reagents or functionalized organozinc halides is described.Using a tri(2-furyl)phosphine-modified rhodium catalyst, the reaction course is altered to hydrozincation when diethylzinc is employed as the organozinc reagent. Trapping of the alkenylzinc intermediates produced in these reactions in further functionalization reactions is possible. Collectively, these processes enable access to a range of multisubstituted enamides in stereo- and regiocontrolled fashion.
