Check Digit Verification of cas no

The CAS Registry Mumber 75438-02-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,4,3 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 75438-02:
(7*7)+(6*5)+(5*4)+(4*3)+(3*8)+(2*0)+(1*2)=137
137 % 10 = 7
So 75438-02-7 is a valid CAS Registry Number.

Direct, Regioselective N-Alkylation of 1,3-Azoles

Chen, Shuai,Graceffa, Russell F.,Boezio, Alessandro A.

supporting information, p. 16 - 19 (2016/01/15)

Regioselective N-alkylation of 1,3-azoles is a valuable transformation. Organomagnesium reagents were discovered to be competent bases to affect regioselective alkylation of various 1,3-azoles. Counterintuitively, substitution selectively occurred at the more sterically hindered nitrogen atom. Numerous examples are provided, on varying 1,3-azole scaffolds, with yields ranging from 25 to 95%.
