Check Digit Verification of cas no

The CAS Registry Mumber 7189-16-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,8 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7189-16:
(6*7)+(5*1)+(4*8)+(3*9)+(2*1)+(1*6)=114
114 % 10 = 4
So 7189-16-4 is a valid CAS Registry Number.

Regioselectivity studies of sydnone cycloaddition reactions of azine-substituted alkynes

Foster, Robert S.,Jakobi, Harald,Harrity, Joseph P.A.

, p. 1506 - 1508 (2011)

The synthesis of azine-substituted pyrazoles by a sydnone cycloaddition strategy is described. Incorporation of a 3-pyridyl moiety at the sydnone N-atom has little effect on either reactivity or regioselectivity, however, 2-ethynyl-pyridine and -pyrimidin
