Check Digit Verification of cas no

The CAS Registry Mumber 7157-52-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,5 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7157-52:
(6*7)+(5*1)+(4*5)+(3*7)+(2*5)+(1*2)=100
100 % 10 = 0
So 7157-52-0 is a valid CAS Registry Number.

UNUSUAL TRANSFORMATIONS OF ARYLHYDRAZONOYL CHLORIDES OF ETHYL OXALATE

Lozinskii, M. O.,Bodnar, V. N.,Konovalikhin, S. V.,D'yachenko, O. A.,Atovmyan, L. O.

, p. 2388 - 2390 (2007/10/02)

X-ray diffraction structural analysis, IR, 13C NMR, and PMR spectroscopy was used to establish that the products of the reactions of arylhydrazonoyl chlorides of ethyl oxalate and sodium ethylate are 1,4-diaryl-3,6-dicarboethoxy-1,4-dihydro-1,2,4,5-tetrazines and 1-aryl-3-carboethoxy-4-arylhydrazono-5-pyrazolones.
