Check Digit Verification of cas no

The CAS Registry Mumber 1567951-78-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,7,9,5 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1567951-78:
(9*1)+(8*5)+(7*6)+(6*7)+(5*9)+(4*5)+(3*1)+(2*7)+(1*8)=223
223 % 10 = 3
So 1567951-78-3 is a valid CAS Registry Number.

A copper-catalyzed coupling reaction of vinyl halides and carbazates: Application in the assembly of polysubstituted pyrroles

Zhou, Chengang,Ma, Dawei

supporting information, p. 3085 - 3088 (2014/03/21)

CuI-catalyzed coupling of vinyl halides with carbazates gives N-protected N-alkenylhydrazines, which are condensed with ketones under acidic conditions to give polysubstituted pyrroles. The pyrrole synthesis may go through a similar mechanism with Fischer indole synthesis, which involves a [3,3]-sigmatropic rearrangement and other reactions. The Royal Society of Chemistry.
