Check Digit Verification of cas no
The CAS Registry Mumber 255897-36-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,5,8,9 and 7 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 255897-36:
(8*2)+(7*5)+(6*5)+(5*8)+(4*9)+(3*7)+(2*3)+(1*6)=190
190 % 10 = 0
So 255897-36-0 is a valid CAS Registry Number.

The Concise Synthesis of Unsymmetric Triarylacetonitriles via Pd-Catalyzed Sequential Arylation: A New Synthetic Approach to Tri- and Tetraarylmethanes
Nambo, Masakazu,Yar, Muhammad,Smith, Joel D.,Crudden, Cathleen M.
, p. 50 - 53 (2015)
The selective synthesis of multiarylated acetonitriles via sequential palladium-catalyzed arylations of chloroacetonitrile is reported. The three aryl groups are installed via a Pd-catalyzed Suzuki-Miyaura cross coupling reaction followed by back-to-back C-H arylations to afford triarylacetonitriles in three steps with no over-arylation at any step. The triarylacetonitrile products can be converted into highly functionalized species including tetraarylmethanes. This new strategy provides rapid access to a variety of unsymmetrical tri- and tetraarylmethane derivatives from simple, readily available starting materials. (Chemical Presented)
