Check Digit Verification of cas no
The CAS Registry Mumber 64218-50-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,2,1 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 64218-50:
(7*6)+(6*4)+(5*2)+(4*1)+(3*8)+(2*5)+(1*0)=114
114 % 10 = 4
So 64218-50-4 is a valid CAS Registry Number.

Bromothiophene Reactions. II. A Novel Rearrangement in the Zinc and Acetic Acid Reduction
Alvares-Insua, A. S.,Conde, S.,Corral, C.
, p. 713 - 716 (2007/10/02)
The elimination of the α-bromine atoms of the bromothienylethanolamine derivatives 2a, b, c, d with zinc and acetic acid unexpectedly involved a migration of the ethanolamine side chain from the 3 to the 2 position in the thiophene ring.Experiments carried out with simpler analogous compounds 3, 4 and 6 seem to indicate that this rearrangement takes place only in those cases in which the carbon atom of the side chain next to the ring supports an oxygen atom capable of being protonated in the reaction medium.A tentative mechanism is proposed to explain the experimental results.
