Check Digit Verification of cas no

The CAS Registry Mumber 256943-52-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,9,4 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 256943-52:
(8*2)+(7*5)+(6*6)+(5*9)+(4*4)+(3*3)+(2*5)+(1*2)=169
169 % 10 = 9
So 256943-52-9 is a valid CAS Registry Number.

Synthesis of arcyriarubine regioisomers by Pd(0)-catalysis or via lithiated indole derivatives - Conformational analysis by semiempirical and X-ray methods

Mahboobi, Siavosh,Dove,Kuhr,Pongratz

, p. 820 - 827 (2007/10/03)

Regioisomers of arcyriarubines were synthesized by the reaction of N- protected indoles with dibromomaleimide either in the presence of a Pd(0)- catalyst or n-BuLi. Methods for N-alkylation of these bisindolylmaleimides and deprotection of the indole-N ar
