Check Digit Verification of cas no

The CAS Registry Mumber 27428-34-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,4,2 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 27428-34:
(7*2)+(6*7)+(5*4)+(4*2)+(3*8)+(2*3)+(1*4)=118
118 % 10 = 8
So 27428-34-8 is a valid CAS Registry Number.

Fluorodecarboxylation, rearrangement and cyclisation: the influence of structure and environment on the reactions of carboxylic acids with xenon difluoride

Ramsden, Christopher A.,Shaw, Maxine M.

experimental part, p. 3321 - 3324 (2009/08/09)

The reactions of structurally diverse carboxylic acids with XeF2 in both CH2Cl2/Pyrex and CH2Cl2/PTFE have been studied. Pyrex appears to be a very effective heterogeneous catalyst for an electrophilic mode of reaction of polarised XeF2, leading to rearrangement, cyclisation and cationic products. In CH2Cl2/PTFE, fluorodecarboxylation is the main mode of reaction, in accordance with previous studies, and may occur via a SET reaction of unpolarised XeF2.
