Check Digit Verification of cas no

The CAS Registry Mumber 55249-92-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,2,4 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 55249-92:
(7*5)+(6*5)+(5*2)+(4*4)+(3*9)+(2*9)+(1*2)=138
138 % 10 = 8
So 55249-92-8 is a valid CAS Registry Number.

Visible-light-accelerated pd-catalyzed cascade addition/ cyclization of arylboronic acids to γ- And β-ketodinitriles for the construction of 3-cyanopyridines and 3-cyanopyrrole analogues

Patel, Bhisma K.,Rakshit, Amitava,Kumar, Prashant,Alam, Tipu,Dhara, Hirendranath

, p. 12482 - 12504 (2020)

The one-pot synthetic strategies for 2,4,6-triarylnicotinonitriles and 2,5-diaryl-1H-pyrrole-3-carbonitriles have been accomplished via a Pd-catalyzed coupling of arylboronic acid with 2-(3-oxo-1,3-diarylpropyl)malononitrile and 2-(2-oxo-2- arylethyl)malo
