Check Digit Verification of cas no

The CAS Registry Mumber 77064-52-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,0,6 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77064-52:
(7*7)+(6*7)+(5*0)+(4*6)+(3*4)+(2*5)+(1*2)=139
139 % 10 = 9
So 77064-52-9 is a valid CAS Registry Number.

REACTIVITIES OF HETEROCYCLIC COMPOUNDS IN NITRATION. 5. KINETICS OF NITRATION OF 5-SUBSTITUTED 2-PICRYLAMINOPYRIDINES

Sharnin, G. P.,Falyakhov, I. F.,Khairutdinov, F. G.

, p. 1234 - 1238 (2007/10/02)

The kinetics of nitration of 5-bromo-, 5-chloro-, and 5-nitro-2-picrylaminopyridines in 80-96percent sulfuric acid were studied by a spectrophotometric method.The kinetic parameters of nitration were calculated.The UV spectra of the neutral and protonated forms in aqueous sulfuric acid solutions were identified.It was established that the indicated compounds are nitrated in the protonated form.The relative (as compared with benzene) rates of nitration were calculated.
