Check Digit Verification of cas no
The CAS Registry Mumber 2199-43-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,9 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2199-43:
(6*2)+(5*1)+(4*9)+(3*9)+(2*4)+(1*3)=91
91 % 10 = 1
So 2199-43-1 is a valid CAS Registry Number.

An unusual dehalogenation in the Suzuki coupling of 4-bromopyrrole-2-carboxylates
Handy, Scott T.,Bregman, Howard,Lewis, Jennifer,Zhang, Xiaolei,Zhang, Yanan
, p. 427 - 430 (2007/10/03)
An unusual dehalogenation of 4-bromopyrrole-2-carboxylates under Suzuki coupling conditions has been observed. This dehalogenation can be suppressed by protection of the pyrrole nitrogen. Using a BOC protecting group, not only is dehalogenation suppressed
