Check Digit Verification of cas no
The CAS Registry Mumber 831203-13-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,1,2,0 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 831203-13:
(8*8)+(7*3)+(6*1)+(5*2)+(4*0)+(3*3)+(2*1)+(1*3)=115
115 % 10 = 5
So 831203-13-5 is a valid CAS Registry Number.

Application of 1,1-ADEQUATE, HMBC, and Density Functional Theory to Determine Regioselectivity in the Halogenation of Pyridine N-Oxides
Hwang, Tsang-Lin,Bartberger, Michael D.,Chen, Ying
, p. 1956 - 1959 (2016/06/01)
The 1,1-ADEQUATE spectrum clearly shows specific two-bond proton to carbon correlations to unequivocally distinguish the major and minor regioisomers of ortho-halogenated pyridines and to aid in assignment of the corresponding proton and carbon chemical shifts. M06-2X/6-31+G(d,p) free energies of the regioisomeric intermediates arising from deprotonation correctly predict the experimentally observed preference and thus can be used to tune the substituent pattern to yield a desired regiochemical outcome.
