Check Digit Verification of cas no

The CAS Registry Mumber 1392495-45-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,2,4,9 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1392495-45:
(9*1)+(8*3)+(7*9)+(6*2)+(5*4)+(4*9)+(3*5)+(2*4)+(1*5)=192
192 % 10 = 2
So 1392495-45-2 is a valid CAS Registry Number.

Rhodium-catalyzed three-component reaction between silylacetylene and two ketenes leading to 1,3-enynes bearing a carboxylic ester group via double insertion of ketenes

Ogata, Kenichi,Ohashi, Itsuki,Fukuzawa, Shin-Ichi

supporting information; experimental part, p. 4214 - 4217 (2012/10/08)

The first cross-reaction between a terminal silylacetylene and two ketene molecules leading to 1,3-enynes bearing a carboxylic ester group via double insertion of ketenes is achieved using a cationic rhodium complex catalyst. This reaction is applicable for various symmetrical and unsymmetrical ketenes with good stereoselectivities.
