Check Digit Verification of cas no
The CAS Registry Mumber 87931-27-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,9,3 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87931-27:
(7*8)+(6*7)+(5*9)+(4*3)+(3*1)+(2*2)+(1*7)=169
169 % 10 = 9
So 87931-27-9 is a valid CAS Registry Number.

Degradation of O-Arylisoureas in Alkali: A Low-temperature Chapman-type Rearrangement
Suttle, Nicola A.,Williams, Andrew
, p. 1369 - 1372 (2007/10/02)
NN'-Di-isopropyl-O-arylisoureas are demonstrated to rearrange intramolecularly to the corresponding NN'-di-isopropyl-N'-arylurea in alkaline solution.The large negative Broensted-type βL value (-2.3) for the reaction measured against the pK of the corresponding phenol and a modest entropy of activation are consistent with a 1,3-aryl migration.The high efficiency of the migration compared with that of the Chapman rearrangement of O-aryl imidoethers is attributed to the greater internal nucleophilicity of the imino nitrogen, which in the present case bears a negative charge.
