Check Digit Verification of cas no

The CAS Registry Mumber 1318254-93-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,8,2,5 and 4 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1318254-93:
(9*1)+(8*3)+(7*1)+(6*8)+(5*2)+(4*5)+(3*4)+(2*9)+(1*3)=151
151 % 10 = 1
So 1318254-93-1 is a valid CAS Registry Number.

CuBr catalyzed C-N cross coupling reaction of purines and diaryliodonium salts to 9-arylpurines

supporting information; experimental part, p. 5039 - 5042 (2011/08/07)

CuBr was found to be an efficient catalyst for the C-N cross coupling reaction of purine and diaryliodonium salts. 9-Arylpurines were synthesized in excellent yields with short reaction times (2.5 h). The method represents an alternative to the synthesis of 9-arylpurines via Cu(ii) catalyzed C-N coupling reaction with arylboronic acids as arylating agents. The Royal Society of Chemistry 2011.
