Check Digit Verification of cas no

The CAS Registry Mumber 1567950-70-2 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 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1567950-70:
(9*1)+(8*5)+(7*6)+(6*7)+(5*9)+(4*5)+(3*0)+(2*7)+(1*0)=212
212 % 10 = 2
So 1567950-70-2 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

, p. 3085 - 3088 (2014)

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.
