Check Digit Verification of cas no

The CAS Registry Mumber 1259313-58-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,3,1 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1259313-58:
(9*1)+(8*2)+(7*5)+(6*9)+(5*3)+(4*1)+(3*3)+(2*5)+(1*8)=160
160 % 10 = 0
So 1259313-58-0 is a valid CAS Registry Number.

Cross-coupling reaction on N-(3,5-dibromo-2-pyridyl)piperazines: Regioselective synthesis of 3,5-disubstituted pyridylpiperazines

Hikawa, Hidemasa,Yokoyama, Yuusaku

experimental part, p. 9552 - 9559 (2011/01/12)

Unsymmetrical 3,5-disubstituted pyridylpiperazines were prepared from tribromopyridine in three coupling reactions. Key to the success of the syntheses is the palladium-catalyzed regioselective cross-coupling reaction in the 3-position of N-(3,5-dibromo-2
