Check Digit Verification of cas no
The CAS Registry Mumber 279-42-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,7 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 279-42:
(5*2)+(4*7)+(3*9)+(2*4)+(1*2)=75
75 % 10 = 5
So 279-42-5 is a valid CAS Registry Number.

ASYMMETRICAL NITROGEN-40; GEMINAL SYSTEM-26. N-CHLOROHYDRAZINES
Shustov, G. V.,Tavakalyan, N. B.,Kostyanovsky, R. G.
, p. 575 - 584 (2007/10/02)
The factors determining the kinetic and thermodynamic stabilities of N-chlorohydrazines are discussed.Acyclic N-chlorohydrazines exist only as trialkyldiazenium chlorides 3a,b.Chlorination of 2-acyl-1,1-dimethylhydrazines 6a,b gave 1,4-diacyl-2,3-dimethylhexahydro-1,2,4,5-tetrazines 7a,b via hydrazyl radical intermediates, and chlorination of a 1-phenylpyrazolidin-5-one 8 gave phenylazoisovaleric esters 9a,b.Stable N-chlorohydrazines were obtained from bicyclic hydrazines; viz. the 2-chloro-1.2-diazabicyclo(2.2.2.)octan-3-one 12 and 7-chloro-1,7-diazabicyclo(2.2.1)heptane 16.The restricted inversion of N(7) in 16 and its 1-methyl quate rnary salt 21 were observed in the 13C-NMR spectra.The acyclic N-chlorohydrazinium salt 25 was isolated.
