Abstract: We present some variants of the Kaplansky condition for a KHermite ring to be an elementary divisor ring. For example, a commutative KHermite ring is an EDR iff for any elements such that there exists an element such that , where . We present an example of a Bézout domain that is an elementary divisor ring but does not have almost stable range , thus answering a question of Warren Wm. McGovern.
