Check Digit Verification of cas no

The CAS Registry Mumber 2111-54-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,1 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2111-54:
(6*2)+(5*1)+(4*1)+(3*1)+(2*5)+(1*4)=38
38 % 10 = 8
So 2111-54-8 is a valid CAS Registry Number.

Novel and efficient transformation of enamides into α-acyloxy ketones via an acyl intramolecular migration process

Zhou, Xiaoqiang,Ma, Haojie,Cao, Jinhui,Liu, Xingxing,Huang, Guosheng

supporting information, p. 10070 - 10073 (2016/11/06)

Hydrogen peroxide and anhydride mediated transformation of enamides to afford substituted α-acyloxy ketones is described. This transition-metal-free cascade reaction has a broad substrate scope and high efficiency. The acyl intramolecular migration procedure successfully achieved this acyloxylation process under mild conditions and increased the atom efficiency.
