Check Digit Verification of cas no

The CAS Registry Mumber 37541-72-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,5,4 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 37541-72:
(7*3)+(6*7)+(5*5)+(4*4)+(3*1)+(2*7)+(1*2)=123
123 % 10 = 3
So 37541-72-3 is a valid CAS Registry Number.

Calorimetric study of phase transitions in ammonium hydrogen oxalate hemihydrate and its deuterated compound

Fukai, Mari,Matsuo, Takasuke,Suga, Hiroshi

, p. 743 - 752 (2008/10/08)

The molar heat capacities of ammonium hydrogen oxalate hemihydrate and its fully-deuterated compound were measured from 13 to 300 K. A higher-order phase transition was found in each compound. The temperatures and molar entropies of transition are 145.4K (6.01 J K-1 mol-1) and 160.1 K (8.23 J K-1 mol-1) in the protonated and deuterated compounds, respectively, where the mole refers to (NH4HC2O4)2·H2O or (ND4DC2O4)2·D2O. The entropies of the transitions indicate that they are order-disorder transitions, probably related to the ordering of one of the ammonium ions. The pressure coefficient of the transition temperature was calculated by the Ehrenfest relation and the available data of the thermal expansivity of the hydrogenous compound: -2.0 × 107 Pa K-1 in good agreement with a reported value -1.9 × 107 Pa K-1 based on a high pressure experiment.
