Check Digit Verification of cas no

The CAS Registry Mumber 100725-06-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,7,2 and 5 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 100725-06:
(8*1)+(7*0)+(6*0)+(5*7)+(4*2)+(3*5)+(2*0)+(1*6)=72
72 % 10 = 2
So 100725-06-2 is a valid CAS Registry Number.

Polynuclear branched tetrazole systems. 2*. New 2-(5-tetrazolyl) ethyl podands and their NH-acidity

Zubarev,Bezklubnaya,Pyartman,Trifonov,Ostrovskii

, p. 1317 - 1325 (2003)

Nine new polynuclear 2-(5-tetrazolyl)ethyl podands have been obtained by the azidation of the corresponding nitriles. Using Bjerrum distribution functions, the values of pKa1, pKa 2, pKa3, and pKa4 have been determined by a potentiometric method for 14 polynuclear tetrazoles in aqueous and aqueous methanolic solution. The found values lie in the range from 3.5 to 7.5 pH units. The overall rules and the sequence of the ionization of the spatially separated tetrazole fragments in these podand systems are discussed.
