Check Digit Verification of cas no
The CAS Registry Mumber 202344-76-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,3,4 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 202344-76:
(8*2)+(7*0)+(6*2)+(5*3)+(4*4)+(3*4)+(2*7)+(1*6)=91
91 % 10 = 1
So 202344-76-1 is a valid CAS Registry Number.

Palladium-catalyzed total synthesis of the antibiotic carbazole alkaloids carbazomycin G and H
Knoelker, Hans-Joachim,Froehner, Wolfgang
, p. 173 - 175 (2007/10/03)
A highly efficient palladium-catalyzed synthesis affords carbazole-1,4-quinones which can be transformed directly into the carbazomycins G and H and are shown to represent precursors for several other biologically active carbazole alkaloids.
