Check Digit Verification of cas no

The CAS Registry Mumber 1269425-66-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,9,4,2 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1269425-66:
(9*1)+(8*2)+(7*6)+(6*9)+(5*4)+(4*2)+(3*5)+(2*6)+(1*6)=182
182 % 10 = 2
So 1269425-66-2 is a valid CAS Registry Number.

Remote chiral induction in vinyl sulfonium salt-mediated ring expansion of hemiaminals into epoxide-fused azepines

Yar, Muhammad,Unthank, Matthew G.,McGarrigle, Eoghan M.,Aggarwal, Varinder K.

, p. 372 - 375 (2011)

The planet of the azepines: Epoxy-fused azepines have been synthesized in a highly selective reaction with hemiaminals and vinyl sulfonium salts. Stereochemistry is controlled by the substituent at the four- or five-position of the hemiaminal. The key step involves ring-opening of the hemiaminal, conjugate addition onto a vinyl sulfonium salt, and epoxidation of the aldehyde by the in situ formed sulfur ylide. Copyright
