Check Digit Verification of cas no
The CAS Registry Mumber 40790-21-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,7,9 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 40790-21:
(7*4)+(6*0)+(5*7)+(4*9)+(3*0)+(2*2)+(1*1)=104
104 % 10 = 4
So 40790-21-4 is a valid CAS Registry Number.

Regioselective synthesis of trialkylpyrazines via nickel-catalyzed Negishi cross-coupling of pyrazine triflate

experimental part, p. 1631 - 1636 (2012/06/30)
A regioselective synthesis of trialkylpyrazines via nickel-catalyzed cross-coupling reaction of pyrazine triflate is reported. The 5-substituted 2,3-dimethylpyrazine derivatives including trail pheromone components of the ant Eutetramorium mocquerysi have been successfully synthesized in good yields by nickel-catalyzed Negishi cross-coupling reactions of pyrazine triflate mediated by alkyl and arylzinc halides.
