Check Digit Verification of cas no

The CAS Registry Mumber 1394252-79-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,4,2,5 and 2 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1394252-79:
(9*1)+(8*3)+(7*9)+(6*4)+(5*2)+(4*5)+(3*2)+(2*7)+(1*9)=179
179 % 10 = 9
So 1394252-79-9 is a valid CAS Registry Number.

Mechanism of the regio- and diastereoselective ring expansion reaction using trimethylsilyldiazomethane

Sakai, Takeo,Ito, Satoshi,Furuta, Hiroki,Kawahara, Yuki,Mori, Yuji

supporting information, p. 4564 - 4567 (2012/11/07)

An equatorial attack of TMS-diazomethane was determined to be the first step of the BF3-promoted ring expansion reaction of six-membered ketones using TMS-diazomethane. The migration reaction occurred in a conformation in which the carbonyl oxygen and the TMS group were antiperiplanar to predominantly afford trans-seven-membered ketones.
